They don't have to be motivated by ethics. I'm fine with them grudgingly doing ethical things because their customer base is all artists, many of whom would look for an alternative product.
You are fine with it, of course, because you're reasonable. But OP's claim was that Adobe is "trying to be ethical with its AI training data and no one seems to even care" as if we're meant to give special consideration to a company for doing the only economically sensible thing when most of its customers are artists.
The great thing about loudly painting Adobe with the brush of "ethical AI training" (regardless of why they're doing it) is that the backlash will exponentially bigger if/when they do something that betrays that label. Potentially big enough to make them reverse course. It's not much, but it's something.
