Been there, done that. That's why I stopped actively contributing open source many years ago. Not because I discovered my code without any mentioning in appliances from heavily subsidized Chinese company, but because nobody gave any s*t, even my own employer. "Stop whining, it's too_good_to_be_true cheap stuff!"
Prusa Slicer was forked from Slic3r. That's kind of the point of free software; fork it, change the colors, stick your name on it. (Prusa has done a lot more than that, of course.)
Frankly, the less software that hardware companies write, the better. They already have their hands full with the firmware and probably don't need to be setting up CI infrastructure for Linux/Mac/Windows and all that stuff.
