I mean sort of. While I get what you are saying but it seems a bit weird, as long as the person isn’t being fired for being part of a protected class I see no issue with a company trying to distance themselves from someone who function is to be a “Brand Mascot” where what they say will be associated with the company hiring them. Fame is a rather fickled thing and reputation sort of plays into the worth of a “celebrity”, like sure behind closed doors these asshats can be as vile and shitty as they want to be but the second they are exposed in the public, the public’s desire to see said person probably drops dramatically since they are isolating a section(s) of the audience who will be wanting to watch something with them in it.

Hell a decent example would be Ellen Degeneres, after it came out publicly that she was a bit of a cunt to her workers. The rating for her show dropped quite a bit (apparently about 40%) after the backlash leading to many of her side shows getting canned and her not getting renewed for a new season for her talk show. At the end of the day its just a big popularity contest where everyone is vying for people’s attention in an already saturated market.
