Model weights can't really be described as source code though. The equivalence isn't exact, but I'd describe the weights more as the compiled binary, with the training data & schedule being the source (which is sort of under an open source license, with the complication of LAION's "it's just links"). The fact it costs $1 million to "compile" isn't relevant.
This isn't to defend Stability particularly though - they've been getting increasing slow and restrained in their model releases. Charitably because they're attracting a lot of heat from political and anti-AI aligned groups. Uncharitably because they've taken a lot of funding now.
