he's not the first to even do this... Snapchat added a premium tier with actual (small) perks way ahead of others, and they have 2.5M subs for it. telegram did it too. People only focus on musk cause he's loud but he's following the trends of the industry, he's not inventing the ideas from thin air. Remember when he said he'd make twitter a "super app"? kinda like how IG, wechat, Snapchat and others have been for a while.
