Interesting, I didn't look at it. Tbh it sounds ridiculous in general to claim a government is Nazi for trying to make the official language survive (especially in the case of Estonian). It also shows how clueless some people are, as if they actually knew what they were talking about they would know that in Estonia for example Russian is very used in Tallinn, local newspapers are printed in both languages, etc. While in Ukraine you actually needed Russian to study in certain universities even (like in Odesa).
Either way, I doubt any argument would work for tankies, that's a cult.
So he complains about laws that would make privacy worse and your take is that he wants to sell data.
Your "suspicion" is based on...?
