I think there's no global intent. There's no formalized group that has a weekly agenda of "Destroy Opensource!"

Right and this is what I mean by the crusade/rage mob analogies. Somebody gets upset about something, and they may be genuinely offended (and still wrong), so they go to Reddit/Twitter/etc and create a post "I can't believe X is doing Y! They're evil and we should stop them!"
Now, there's a whole bunch of people who don't have nuanced well researched opinions on X or Y. They just want to be upset and have a good fight, and this is a nice convenient thing that feels just to fight about. So they hop on and start jumping in on a side. This is why I use the crusade analogy - you don't care about the pretense, you're just in it for the battle.
The issue with rage mobs, whether it's in regards to the open source community or what broadcasters can air on television, are purely destructive. They don't care about fixing problems, they have no interest in improving the community or advancing things, they simply want to join in a fight and express anger. If a rage mob gets it's demands (you cancel that sitcom that portrays a gay family positively) then the mob doesn't go away - it just finds something else to attack and eventually it attacks itself.
