> not like they changed anything significant about the product itself

They had already done this months ago, they changed the licence and stripped a lot of the code of their admin UI/object browser. So a lot of the features vanished for people overnight if they updated. This is what the OP is linked to - a fork at the point that they did this. This was work already done, feature already widely in use, they decided to take it out of what was available to the community.

So the product has significantly changed and offering had been reduced. That in addition to the stopping of publishing images - both without notice - caused a decent bit off community 'wtf'.
