I think it's going to be a challenge, but there is a valid rationale here. The reason Warren or others would look at Amazon, Facebook, and GOogle, oversay, Disney, is because their products are so completely different and Disney is just not at the same level as those companies for controlling every day activities in your every day life. Disney is irrelevant here. THey own media properties, theme parks, movies, consumer goods, their own content delivery network, and those are irrelevant to your daily life. You could cut Disney out of your life and you'd lose their entertainment properties, big deal. You can't live a modern life and realistically cut Amazon or Google out of your life, even if you never shop on Amazon or only use DuckDuckGo (or Firefox, or w/e), your daily fingerprints are all over Amazon and Google products in ways that you don't even know it's Amazon and Google.
A huge portion of your daily web activity is on Amazon. No, not Amazon.com, on AWS - Amazon Web Services. You pretty much can't use the modern, Western internet without AWS. It is everywhere. Amazon has challengers in this area from Microsoft, and then you've got Google in a distant third, and then a smattering of other smaller companies. But, Amazon really owns the lionshare of "new" companies with cloud infrastructure, because their products are so good.
For GOogle, they've made such a good product that they own an actual majority on search traffic. Google has not abused their role in Search for consumers, they still provide the best search engine, at no cost, and the product is excellent. Google Search provides legitimate results, even when Google fails to implement search effectively for their other products (I've talked about this before, but search "Feminism" in Google and you'll get accurate, historical, informative articles and web pages about Feminism; Now search "Feminism" in YouTube... Note how different the results are despite that this is the same company building these two search algorithms). While Google has been an agent for good in the search game, literally knowledge sharing on the internet would not be what it is without Google, their is tremendous risk for abuse. Beyond that, Gmail, Android, Photos, and more, Google has built this huge cohesive network of data collection that makes their products exponentially better than everybody else's.
For Facebook, Facebook owns the three largest social networks in the world: WhatsApp, Facebook, and Instagram. A case can be made that Facebook has made Instagram better for consumers: Instagram used to have major problems with scaling and the network has only gotten more popular since Facebook bought it. Facebook, undoubtedly, abuses their position. While Amazon and Google arguably do not abuse their positions, Facebook unabashedly does... They hire counter-intelligence firms to spread false, damaging information about people who criticize them; they work with bad actors around the globe; they profit on misinformation, and promote misinformation because it's more profitable.
Disney isn't in the same realm here. They're not even relevant to this conversation. If you're worried about an entertainment company damaging consumers with a monopoly, look to Netflix, not Disney. Netflix owns the entertainment market today. Apple isn't either. Apple makes stuff, not services. AT&T/DirectTV can pose a danger, but they're quickly becoming less and less relevant.
I'd recommend people listen to a recent interview with former Hollywood studio Exec Barry DIller on RecodeDecode with KAra Swisher. It's typical rambinling shotgun question style of Swisher, but Diller makes a lot of really strong points, chief among them that the classic studios are irrelevant.

The trouble with the monopoly argument against Google and Amazon is that even if you hate these companies for whatever reason, their main products that give them the most influence -- AWS for Amazon and Google Search for Google -- are still agents of good. AWS made cloud infrastructure approachable for consumers, startups, and major companies... It offered a consumer service that was previously only available if you
were an Amazon or Microsoft. Microsoft and Google followed suit with their offerings. I actually prefer Google's products here (I fucking love Firebase, which Google bought in 2014 and has continually made better and better). Today's interpretation of breaking up monopolies usually targets businesses that hurt consumers with their monopoly, and the argument cannot be made that AWS and Google are hurting consumers with their monopolies... They simply
aren't. But, anti-trust law did not always take this Corporation -> Consumer relationship as the primary motivation for whether an anti-trust suit has to be brought... Standard Oil wasn't broken up because of it's Corporation -> Consumer relationship, it was broken up because of its abuse of other corporations. But, Anti-trust law started to change in the 1970s, 80s, and 90s (rejected Supreme Court nominee Robert Bork has basically defined our modern anti-trust understanding), and now what we know as anti-trust law puts the consumer -- you, me, the small business -- as the chief plaintiff in anti-trust, and in that cases, it's almost impossible to make the case against Amazon and Google to be broken up. Interpretation of anti-trust would have to go back to pre-1980s interpretation.
I legitimately think that Facebook is an agent of evil, though, so I wouldn't extend that umbrella of defense to them. And, to be sure, I'm not defending Google or Amazon, I'm saying that our present day interpretation of anti-trust would be a challenge to break these companies up, and we'd have to go back to a early 20th century vision of anti-trust to do it.
