TL;DR: using AI as an addition is great, using it to replace people is not. For solo indie developers without a budget it's always an addition, for AAA it's almost never.
The difference is this:
AI allows this indie game to exist; without, it simply would not. Nobody's loss in having one more game.
AI allows AAA studios to save on/fire a part of the development team required to create the game; without, they would have been hired. That's a loss to the people working in the industry and no gain, since the game would have been developed either way.
That's the same as with artists. Any artist that lost a job to AI will tell you they're not happy about that, while they'll not care about AI usage for projects they wouldn't have been hired for anyway.
Of course, there are AAA studios that handle AI sensibly, so technically it's not strictly related to AAA itself, but the overwhelmingly vast majority just replaces expensive labor with it to save money.
