Yeah, TV is an ok analogy I guess. It's indirect compared to directly purchasing a show on the creator's website. It's indirect compared to other ways of micropayment, be it direct donation to the author, flattr, patreon, whatever.
What's even worse is, investors are not informed upfront that, in fact, a portion of their investment is going to be donated to content creators, and they will only get that money back if more new investors join the platform.

About your second point, I agree, the pyramid may fall in slow motion. It largely depends on how those at the top of the pyramid decide to cash out - as they hold the vast majority of tokens. They may slowly sell over the years, or power down and accumulate the tokens for a while then suddenly dump to the market.
Either way, we're arguing time frames here - the mechanics stay the same.
