Nope. Those model releases only open source the equivalent of "run.bat" that does some trivial things and calls into a binary blob. We wouldn't call such a program "open source".

Hell, in case of the models, "the whole stack to run the software" already is open source. Literally everything except the actual sources - the datasets and the build scripts (code doing the training) - is available openly. This is almost a literal inverse of "open source", thus shouldn't be called "open source".
