I hope they got paid, I will be very sad if they didn't at least get G5 money.
OpenClaw notably was built around Mario Zechner's pi[0]; uv I believe was highly adapted from Armin Ronacher's rye[1], and uses indygreg's python-build-standalone[2] for distributing Python builds (both of which were eventually transferred to Astral).

I guess it's kind of a shame that a lot of the financial value for UV is added by people who won't see any of that - it seems like that's a wider open source problem/question to be honest.
