For almost 3 years, Adam and BLAB were like 3 peas in the Disney pod. They collab a lot in that time and ended up being roommates. I suspect Adam considers Spencer at least a kindred soul - a goofball Disney adult. I think he tolerated Katie's obnoxious behavior because she was with Spencer. According to a Tattler that apparently talked to him, he said he wants to help them reach 100K subs.
When Adam began showing more of Daphne in his videos, you can see Katie didn't care for her. And BLAB wouldn't show Adam and Daphne at all in their videos. Not sure how Adam felt about it, but he seemed to accept that for a time.
After the apartment fiasco, when they haven't been seen together since, Katie kept name dropping Adam's name and claim that they text daily. It was when Adam and Daphne appeared with Griftbuster in a photo, that BLAB started cutting ties, unfollowing him on other platforms, filtering his names from comments, etc.
I am certain that Adam's recent post was probably done at Brickey's urging for the good of the vlogging community to avoid a repeat of Princess Nite happening at Tron.
Adam tried to clarify the money situation from the apartment fiasco. Though he downplays it, he was caught off guard when they bolted. I think it did hurt him people he considers friends would do that. And so far this all had nothing to with Daphne. If anything, Adam bend over backwards to accommodate their preference not to show her in their vlogs. It was months later when Katie claimed she was "assaulted" on the Columbia, that Daphne spilled the tea on what went down.
Yeah, it was foolish of Adam to post since it just reopen a can of worms.
