As long as their clients can redistribute it, its not illegal, especially if their clients have 0 interest in leaking the source code, the real trick is, has anyone who is NOT using that client hit any of the AGPL relay servers?

For context, I worked for an employer that sold a custom software solution, which used GPL'd software, client was in the military space, so I guess DOD, anyway, for over a decade nobody asked for any of the code, till some years back. I am guessing they just wanted to have it evaluated, but it was a workhorse of many many things, good luck trying to fork it, LOTS of moving pieces involved.

Nothing illegal unless someone who touches a TM SGNL server (somehow) requests the source and they reject you from having it.

Yes, that's what I meant by the possibility of them only offering source under AGPL to paying customers. Oddly enough, I'm familiar with that in the completely different context of davisr's reMarkable Connection Utility, and the model can work reasonably.

But from their website, which has terms of service for each app, it really seems that they are presenting them as standard proprietary closed-source offerings.
