They're not under any obligation legally - but they've been intentionally misleading at every step to try to make Apollo the bad guy
Yes, but he also should listen to Ru Paul and not duck it up. Or maybe not digg it.
Putting aside why Reddit's behaviour is objectionable. Reddit did this in a way that will cost them money and harm both their reputation and quality.
Had they set out a reasonable timeline for the new prices, they would have had a new revenue stream. Instead they killed it and at the same time created an incentive for some of their most active users to leave.
How long will Reddit survive if they don’t do this? I have no idea. But I do know the CEO has to deliver more than happy users.
