I think the interesting "what happened" is about the consequences - has there been some objective drop in uptime/performance/errors or some other technical metric?
Which security breach are you referring to? I'm not aware of any major ones that have happened since the acquisition, but this one seems to be the one people point to even though it happened prior.

Sure, but I feel like this was because of feature creep more than anything else.
Most common thing people use it for is posting and reading. If you fake feeds as if they are real-time then the viewer will never know there was a system outage.
I am almost positive there was a massive security breach too.
