"Open source" and "commercial" aren't opposites, plenty of models we consider commercial are also 'open source' - an obvious example being Facebook/Meta's models...
Looking outside of AI there's plenty more examples. Chromium is open source, does that mean it and Google's Blink web rendering engine is non-commercial? I'd say no.
Should also be noted that there's been some pushback recently on whether models trained on closed sources should be called "open source", just because the model itself is.
