Is it realistic to sue Russian Railways for violating the license of a synthesis model from the silero-models repository?

I saw the news about the virtual assistant “Valera”, which was just presented by Russian Railways. Judging by the voice, our voice has been taken aidar from repository silero-models … published under a non-commercial under licensed CC BY-NC-SA.

Compare the voice here:

And here:

Obviously, when we laid out the model, we were well aware that this could have consequences. Of course, we are flattered that Russian Railways has made its choice in favor of our model, but this does not negate the fact that the license was violated.

Usually companies apply for customization or improvements. Or simply buy a license for the commercial version of the software. But in this situation, apparently, Russian Railways employees (or contractors) simply didn’t give a damn about the license … or they simply didn’t read it (we all guess how business processes work in such companies).

Another question for the community, is it worth investing in litigation in this particular situation, or leave the situation at the level of public discussion and try to draw maximum attention to it? Maybe you have already found yourself in a similar situation – please share your experience.

Last time, in a similar situation, opinions diverged (and the bank immediately came running in the comments saying oh, we don’t use it anymore, you misunderstood us): part of the community drowned because the then GNU AGPL license essentially does not protect such releases from commercial use , the part that the bank is wrong. But for this reason, the model license was changed to CC BY-NC-SA, and it seems like there should be no doubt now.

Raise, please, to the top.
