I totally get that and personally would never hold that against him. Nor did I interpret it as a threat.
However, this comment chain was of how vulnerable non commercial projects like it are to outside factors making causing exactly this issue, making further maintenance on the project infeasible... Consequently ending it, effectively.
There is no blame in play here. haunter merely quoted this as a reason for why theyre worried about it longevity - and considering there was a discussion about an upstream change which would've realized his worry... It seems not at all misrepresented?
Fwiw, I personally don't share the same worry as haunter, because I don't see the chosen distribution nor OS as a significant investment. I feel comfortable switching things around occasionally
