Stallman said that the training data is not relevant as long as the
network can be tweaked by retraining, i.e. the weights are licesenced so
that modifications are allowed.

Is this even practically possible? How do you re-train a blob you know
nothing about? To me this sounds similar to saying a compiled binary
is free software if the license allows you to decompile it and
deobfuscate it.
