Yeah, I find it extremely off putting how they feel so confident to declare ownership over content we all gave them and built for free. Worse, at the same time they accuse US of being freeloaders! If I'm contributing free content I expect at a minimum some respect and civility in return, not being treated like some free slave labour.
They came after a small sub I moderate today too. My response was to make a sticky post to the sub with the contents of the mod mail and a recommendation for everyone to move to kbin or lemmy. I hadn't planned on giving reddit any more free content anyways given their behaviour.
