Edit: To clarify:
Is it even possible, financially speaking, to keep adding storage? I mean, advertisements don’t even make a lot of money, is the indefinite growth of server storage even sustainable?
Or will they do what Twitch does with old content and just delete them?
i imagine they will delete content. they have already started deleting google accounts with 2 years of inactivity.
That specifically excludes accounts with YouTube channels though, if I remember correctly
