Not really a good comparison. WordPress is comparable because it comes with the same/slightly different tools for building a business. It’s on the same shelf in the grocery store, so to speak.
I don't think so. YT/Twitch provide the platform and the audience, that's comparable to wordpress.com (in a way; it doesn't really provide the audience).
I don't know of any creators that are leveraging wordpress.com.
Using the software is like using Windows (or Linux, if you want a comparison in open source), but I don't think anyone argues that Linux takes good care of creators in the way they expect it from Twitch or Youtube, primarily because Linux doesn't pay creators, it's not a middle-man, it's a tool. Like wordpress.
