I don't think they're setting any precedent here. It's not a new thing for people and businesses to distance themselves from people who say batshit crazy things like this. You cannot talk like this and be surprised when people want to distance themselves from you:

When I think about all the children Hillary Clinton has personally murdered and chopped up and raped, I have zero fear standing up against her. Yeah, you heard me right. Hillary Clinton has personally murdered children. I just can't hold back the truth anymore. Hillary Clinton is one of the most vicious serial killers the planet's ever seen.
