This kind of things been going on for the last 60 years. At the heart of it is companies distancing themselves from people or products that no long represent them or would otherwise put them in a bad light through affiliation. Usually political but sometimes stances on popular topics.
Id could source multiple times where this same kind of thing happened back in the late 50s till now, but I'm not going to because I know that no matter what I come up with Master Mathew will do what he can to discredit it or claim that it's not the same.
This kind of thing boils down to marketing, and just because it happened to somebody you agree with doesn't mean that the world is ending or some kind of purge is going to happen.
Besides, its no surprise YouTube is doing this either. They've been doing it for a few years.
