Unless you're eating at a local taqueria that makes their own (or you know a friend who makes their own), they're not wrong. Commercial corn tortillas are fucking gross, and I hated them until I had fresh ones.
Better go patronize them quick before their customer base is deported.
Not sure about where you are, but here the staff is more likely to be deported than the clientele. Which is a real shame, I like the staff more than my fellow patrons more often than not.
Fam, keep an eye out for offices with signs that say "Remesas" or "Envios" in the window. Those are places that help you send money back home to Latin America. Then look for a taqueria nearby. Guaranteed to be the best in town. They tend to be nearby so people can send money on their lunch breaks.
