It doesn't require it, but even if some people are doing it on the paid plan - ignoring for the moment that the argument is asinine because this is a fixed recurring payment, not pay-per-use - why do you care? Some people have fun and it involves paying other people; if you're neither, it's still none of your business.
Why so defensive? I never stated any such opinion on it. I just pointed out the fact that it's not some sort of anti-capitalist activity that doesn't involve monetary transactions - billionaires are actively getting richer out of this.

Nobody wants or cares about it being anti-capitalistic. It's just free snacks or up-front pay for an all-you-can-eat buffet. Yes, somebody pays for this, but no, this is not in scope or relevant for people enjoying the meal.

As they should. Yes, we know they are, and it's fine. That is just the fundamental of market economy: someone earns money by providing useful goods or services. It's not a problem in itself, and neither is the fact that there may be a billionaire involved.
Getting wound up about billionaires specifically is a shtick of people who want to sell your eyeballs to advertisers, and/or sell you their ideology. The former is a cancer on modern society. The latter is even worse.
(Yes, there is growing income inequality, unfair concentration of wealth and power, and such. But putting it all on "billionaires" - the modern witches and demons - is just a trick that conveniently redirects any blame from people, organizations and systems contributing most to the core problem.)
