My expectation is that all of the stalking and threats happened due to his own gay panic, whether she actually knew or not.
And my other expectation is that his management, ABC, Fleiss and Co, etc. would have dropped him immediately after Cassie's restraining order was granted were it not for his story. This coming out tour and the subsequent Netflix series is probably a result of a lot of behind the scenes deals that have happened over a long period of time.
I'm guessing everyone professionally close to Colton has known for over a year.
