They are business association much like BSA, and less of an Open Source Steward these days and it is highly concerning the number of open source projects they hovering up under their "protection"
Praat would actually be a good candidate with just 2 people contributing majority of the code.
Record labels argued in court that each song shared in p2p networks that was downloaded at least once entitled them to statutory 150k USD in damages. Using that same logic Praat authors could demand 150k per release of voice.ai software at the very least.
In fact I would really like them to do that - it would fund further development of Praat at least and set a precedent showing that GPL != public domain, which seems to be the perception of many companies including large corporations, simply because nobody will care to enforce it.

Then there is big problems with calling it theft, as legally is it not. Infringement is not theft and in most jurisdictions (if not all) in the US you are barred from calling it theft in court.
