In my gaming circles, people who work on SaaS solutions are against SKG even though they are avid gamers and even open source contributors. They just recoil on a thought of an EOL plan. Same on HN.
"Think of the indies" is just same old "Think of the children" astroturfing.
I feel a carveout for total says, say $200k USD or less, would be reasonable. Otherwise you're just conscripting indie time.
I was working on a game, but I'm not looking forward to releasing updates everytime steam changes their relay. Considering scrapping multiplayer completely.
