Yes the reasoning behind the decision is clear and as you described. But I would also make the point that the decision also comes with certain consequences, to which a discussion about merits is directly relevant.
We're talking about a decision that the people behind QEMU made that affects people, to which the consequences of made the discussion of merits "directly relevant".
If we're talking about something that neither involving QEMU nor the people behind it, where is the relevance? It's just a rant on AI at that point.
Who is going to "overtake" QEMU, what exactly does that mean, and what will it matter if they are?
