Just gonna play devils advocate a bit. While I'm not gonna argue about this being a problem (it is, and should be fixed ASAP), there IS a logical reason for Frisco specifically. Dallas is basically a tech city these days. Most people associate austin with the "little californiia" label, but in reality Dallas is the tech center of Texas. It's larger, has more resources, and a more established base in the industry. Basically, Austin is where all the weird startups go, Dallas is where the established mega companies go and where people from Austin move to when they get big enough.

Frisco specifically is what you'd call a "bedroom community" for Dallas, basically its a city that ONLY exists to serve as a place for Dallas workers to live. See where I'm going here? Giant tech based city? Obviously H1b visas and indians are gonna be a big portion of the main work force. Therefore, the bedroom communities (like Frisco) are gonna reflect that.

I don't LIKE it, and it SHOULD be reversed ASAP, but there IS a logical reason (given the circumstances) for this. Hopefully given the new requirements and standards for H1b visas (like requiring $100K bonds per employee, employers being responsible for any crime they commit, massive fines and legal action for hiring an immigrant when there's an American available for the job, etc.) this type of thing will change quickly and reverse.
