The backlash against loot boxes was strong in 2017, but the results of a Game Developers Conference survey of more than 4500 developers who have attended a GDC event in the past three years strongly suggests that they're not going away anytime soon. 11 percent of developers who responded to the survey said they are currently working on a game that will monetize via the sale of "paid item crates," and some developers say they're necessary to ensure the continued stability of the industry.
Loot boxes are also an integral part of videogame markets outside of North America and Europe, another noted, particularly in China and Japan—which also have laws aimed at protecting consumers from abuse. That reflects the real issue, one developer said, which isn't the loot boxes themselves but how they're implemented.
"Time is money," one developer wrote in follow-up comments. "So long as, A, the content is also accessible by playing the game; and, B, this and all parts of the game are balanced for gameplay first and monetization second, then I see no legitimate basis for complaints."
It's necessary for developers to figure out how to incorporate loot boxes in a way that works for Western audiences, another explained, because straight-up game sales are often not enough to enable the development of games that people want to play. That, in turn, could have a detrimental effect on the industry as a whole.
"Microtransactions have to be a part of your strategy in triple-A gaming. So everyone will need to figure out what works for them," they wrote. "I'm sad [Star Wars] Battlefront [2] got it so wrong. This whole controversy will have a lasting impact on the industry and I am most worried it will affect game creators' jobs more than anything."

Another snippet around F2P/DLC
Across all games, loot box or not, just under half of the developers surveyed said they were releasing a traditional, paid game, with 39% saying their next title would be "free to download." 23% are working on a game with DLC, and 22% are working on something which will sell in-game items for real money.

Panic averted, no one needs to worry they're going away. More confirmation as well devs need them just to be stable. Strong and stable, like Theresa May's Government. Remember, you also have no legitmate basis to complain if the devs tell you they are doing it the proper way.
