Languages are not countries. A pet peeve I have is websites that toggle languages with a flag.

In this case, I would be curious to know if the PRC would have an issue with a traditional character option.

Since traditional is used in Hong-Kong which is in PRC, I doubt they would have an issue with it.

We're not talking about languages here however, but countries. A "traditional character option" wouldn't be enough to indicate Taiwan (since languages are not countries, just like you said).
