It's been clear from day one imo that EGS is all about Tim going after Steam, he is a billionaire after control of an open market, Steam is his biggest threat in that regard, all of his "steam is a monopoly" soundbites point to this.
I would be fine with EGS working as competition against Steam and other storefronts if their store actually benefited the consumer and didn't indulge in practices that negatively impact the consumer but since that isn't the case I will continue to support storefronts that offer more choice.
A few years ago I said the same thing about Microsoft and UWP and their anti-consumer approach to the PC space and since they are now doing amazing things for consumers in this space my opinion has changed and I am fully in support of them.
If Epic change their stance then I will also change mine but until then I will not support them.
Truth be told, GOG is the main service I use because of their DRM free policy but I am always open to more choice as long as it benefits the consumer.
