Babbel, Mondly, Lingonaut.
Babbel is well established, traditional language learning programs, HQ’d in Germany.
Mondly was developed in Romania, acquired by Pearson (UK) but i believe still HQ’d in Romania.
Lingonaut is purely UK but is open source project and values are very much in line with EU as they’re GDPR compliant.
I dont think you know the kind of people you’re trying to moralise over here.
