If you're worried about device fingerprinting, Adobe has far more reliable ways to do it already. Canvas fingerprinting, IP tracking, cookies. A hosts entry tells them almost nothing they couldn't get elsewhere, provides them with almost no entropy, and attributing insidious intent to what is most plausibly a UX feature is conspiratorial.
I'm not worried about this, since I don't use Adobe products. I'm just calling out what's clearly user hostile behavior. Considering the amount of hostility Adobe has exhibited towards its users over the years, I'm inclined to believe this is yet another example. Nothing conspiratorial about that. If anything, calling this a "UX feature" without any evidence either way is suspiciously dismissive.
