Yeah, the mojo pitch is so good, but I don't think anyone has an appetite for the potential fuckery that comes with a closed source platform.

Yes, but Latner said multiple time it's closed until it matures (he apparently did this with llvm and swift too). So not unusal. His open source target is end of 2026. In all fairness, I have 0 doubts that he would deliver.

Given Swift for Tensorflow, lets see how this one goes.

That one did get open sourced but nobody ended up wanting to use it

Who would anyone want to pair a subpar language with a subpar ML framework?

That is the thing, what lessons were learnt from it, and how will Mojo tackle them.
