Youtube is worst than Twitch, so I don't think there's another good platform for Drake except Twitch since the other platforms doesn't popular.
Why is YouTube worse than twitch? They have massive global market share, just not in livestreaming. Their political censorship is overboard but I understand wanting to waive liability from the tech censorship overlords by banning discussion of contentious political topics. Gambling isn't as taboo so it seems like they allow gambling content to be published.
Youtube may block gambling content in countries where gambling is ban. That is the censorship youtube will do on gambling channels. Youtube is playing safe when they remove or banned videos that have political views. They just don't want to have problems with the authority and wanted to make their operation smooth by banning and deleting videos that can offend or attack any political parties. Aside from that, Youtube is a good platform and maybe a good alternative for gambling streamers now that twitch is banning these gambling streamers.
Though we also don't know what will happen if regulators started to pressure youtube to ban gambling streamers since it is highly possible to happen too.
