That means the artists probably have to move somewhere else, which is fine I guess, unless it's only a matter of time before the new site gets too expensive to run and either dies or gets sold off.
Or... it's not a new site, and it all collapses into something like facebook. I am not on it, but it's harder to avoid it. I quit using instagram (for that reason, and because it's toxic) and I do use whatsapp to keep in touch with several friends in different states in a group chat. It does bother me that fb owns them though. It seems like only a few companies will 'own' the majority of the content of the internet, at least in terms of how the masses consume it.
