I dont think this is particularly controversial. I would use open sats model when I’d want my donation to be distributed to different people. If I want one dev that I appreciate to get my sats, I just send sats to that particular dev without any middleman. As long as you contributing to bitcoin devs is up to you how you donate. It’s your money and your decision and there’s no need to use “the best model” or base your decision on a public poll 🙃
