They posted that stuff on move in day. Sure, not the best PR, but they were there for 3.5 months and youtubing became a very real thing with many of the players showing their every day activities or what they did on day offs like going bowling, fishing, pool day, etc. And more importantly, not a single player, coach, etc. got COVID after the initial quarantine. Plus, the current bubble is a developmental league, so they aren't used to nice hotels anyway.
Plus, as
@Legacy said, the big money far outweighs the short-term bad PR.
