You're using the fact that OP CAT isn't activated yet as evidence that it's a marginal idea. Ok.
Saylor's trying to explain why he pushed against ARK ETF funneling money to OpenSats, which Odell called him out for. He's saying that a constant waterfall of money with no strings attached will CREATE Big Protocol, and busybody developers will find ways to tap into that cash flow. This is a very real concern and this type of things happens often in the corporate/nonprofit world. He made a solid argument and a clear explanation for it. I think OpenSats is probably not so easily gamed, at least for the time being, but ETF profit donations may be hard to turn off, so forethought and caution are warranted here.
Still I think people should donate to OpenSats.
