Not sure I agree with this. Beyond a certain level, subscriptions to a given creator are to that creator, not via the platform. It's true that a lot of consumers won't take the effort to follow the brand off platform, but that's not always the case. I think the recent development of the influencer marketing industry as a whole is proof of this.

Of course, how you ever get remotely famous or established in the first place if the content you create is remotely vulnerable to false copyright claims is another question entirely...
