I don’t think that it would have been different if someone else was the president. Pre-Trump I had a vacation in Cuba and since I knew that the internet is a luxury there I made Spanish available offline on Google Translate. Works great, then I made the mistake to launch the app when I hade one hour access to the internet in Havana and puff translate is gone. I’m not allowed to use it there. That surely destroyed the communists.
