mozilla's main problem right now appears to be they just do not recognise that they have pissed users' trust up a wall and now we are suspicious of everything they do.
you cannot, in a position like that, just do things which look dodgy as fuck and expect users to suck it up quietly, whether or not they are as they look.
look, i'm going to put this in simple words that even a mozilla employee could understand:
earn back our trust or die.
mozilla is pretty fucked anyway, they have relied on google buying default search engine placement illegally.
even if they manage to scrape out of this by building back trust, we are all likely to move onto servo at some point.
you may recall moz started servo, then merged part of it into gecko, then abandoned servo.
like they did with rust and some other things. things they've done for the better are the things they are abandoning.
