I think the entire attitude of the author coming in to this is wrong. It's zero sum. It's an assumption that you're either gaining from the platform or the platform is gaining from you. This is wrong. The platform has network effects that make everyone well off. Google owns Youtube, yes it gets enormous value from creating/owning the platform. But Youtube isn't exploiting Mr Beast, Mr Beast also gains enormous value…
But what if Google changes the TOS for YouTube and puts Mr. Beast out of business? Should that guy just retire and be happy with what he got?
This isn't an academic exercise, do we see anyone outside of the platforms gaining the success that the creators inside the platforms do? I'd be happy to note anyone I've just totally missed, but these platforms really do actually work.
