Is this from Reddit?
Wow, if this is true, this situation with Adam is even uglier that I thought. BLAB did a moving video in August 2020 when they announce the move to OC when they signed a 6-month lease. Then at the end of January 2021, Adam did a video showing him moving his stuff around to get ready for his "roommate". Subsequent cross checking of vids from both channels of furniture and the kitchen when Katie did cooking confirmed BLAB moved to Adam's apartment. I did not know they were already living in the same complex.
It would make sense that they would be planning on moving when they were at WDW in October, but never informed Adam then. When they returned to California at the end of October, they held off announcing the "big news" for a couple of weeks. What they had to gain by teasing this, I have no idea, unless they wanted to tell Adam first even though they were with him for a whole month in Florida.
It is believable that Katie would be the "gangster" causing problems with the property manager.
I really hope that they had the decency to pay Adam the extra costs of breaking the lease, but I really doubt they did that. They were hiding from him when they fled to Malibu and then to Vegas.
