I disagree with this also, but the latter was so obviously wrong that I figured I should leave a reply. We are separate projects and what Asahi does is their business, our interactions will be in upstream projects and follow upstream guidelines.
Oh well, if this doesn't pan out, hopefully someone else will vibe code for a week and get it working in the near future.
The engineer and the project have discussed these risks and decided to continue in a fork from Asahi. So I would say that this is (nearly) how it is supposed to go. Asahi stays clean from contagion and Gravity Linux has taken a, hopefully well considered, risk.
If this were the case, then Wine and its forks like Proton would have the same issue.
Former Microsoft employees have contributed to Wine in the past.
