Agree...funding sources can come with baggage. However an ETF owner giving a percentage of proceeds back to Bitcoin devs, isn't bad willed, IMO. Maybe if it was done directly, but it's not being done directly. It's being done indirectly through existing funds.

I don't think with all respect that anyone can tell if it is bad willed untill shady shit starts happening. We tend to forget that #bitcoin was created to literally FIGHT THE WALL STREET AND FED GANGS and now we are close to saying : if they give bitcoin devs some money it is not that bad. ETF are not friends of Bitcoin. There is a lot of wealth in BTC community, why the grants can't come from the "inside"?
I don't trust VCs, bankers, Black Rocks and others. Getting even some control over BTC protocol is the biggest wet dream of representatives of the falling system. Thanks God For Consensus.
