Where are the sources? All I see is binary files.

even meta

Lol, ofc meta, they have the biggest bigdata out there, full of private data.

Most of the opensources are recompilations of existing opensource LLMs.

And the page you've listed is <10b mostly, bar LLMs with huge financing, and generally either copropate or Chinese behind them.

there are barely any. I can't name a single one offhand. Open weights means absolutely nothing about the actual source of those weights.
