No, most developers don't hate anything. Most developers are just normal people makin' stuff because their company pays them to.
Most developers are not particularly ideological.
Just some of us are ... perhaps a little bit more than in other industries.
And normal people do have feelings. So they like or love the things they do, or despise or even hate them. Unless they became mindles zombies along the way.. which happens, but much more common is rather that they project all the other negative feelings into technology X or Y ... at least it often seems like this, when I read another rant about the technology Z.
Facebook is legendary for introducing breaking changes to their API without warning, for having terrible documentation, baroque and inconsistent APIs, flaky behaviour and broken examples.
Whatever you think of Facebook the company, Facebook the API is something everyone I know has horror stories about.
