It goes to $2.5m for 5 million users/subscribers and tops out at $4.5m for 100 million subscribers. It’s not staggered evenly at all IMO. So I worry mainly for the small players. This shouldn’t have any meaningful effect on any big player.
5 million users isn’t a lot unless we’re talking paid subscribers. Their license likely does not make a distinction. For a (free/ad supported) service like a niche YT clone, this could be fatal.
