But Google has the legacy of their "don't be evil" company motto to content with. Which is to say that people expect (foolishly) for them to at least try not to appear evil.
The difference between Google prioritizing Chrome vs anyone else is that Google owns Chrome whereas Apple doesn't, and some random startup certainly doesn't.
It smells of Microsoft's "we'll only make this work in IE and fuck everyone else" strategy and that doesn't bring other warm thoughts to mind.
So it's not JUST that it's fashionable to think the worst of Google these days.
