It's about the disrespect of not asking. Could Firefox have asked if users wanted to enable AI features? Of course they could have, did they? Of course not, just think about how would asking would effect the shareholders!!
I don't disagree with the premise that it's hard to make everyone happy, but the problem isn't about pleasing everyone, it's about treating users with respect, and not jumping on the AI everywhere bandwagon, without asking first. Especially because Firefox has billed itself as privacy protecting, and AI is definitely not privacy focused. One might even say, privacy violating... From the privacy focused browser...
I just wonder if wired fans just never skip forward a song, or adjust the volume. Or even use active noise canceling.
