If, as you are claiming, the Taiwanese don't have their own Taiwanese Mandarin, with their language being just the same as the Mandarin used in China, how can it be that at the same time they also don't get to have a say in what constitutes the "standard" of that "common" language they share with the "mainland?"
Also, there is no reason for constantly calling it "Mainland China" where you could just as well call it "China," unless it is to further a political agenda.
Anyway, this is all beside the point. The concept of a "standard" language is political not linguistic. If Google is run as a business, not a political entity, their linguistic choices should reflect the language actually being used in any given market, and not be based on purported "standards" promulgated elsewhere. The same simple concept that somehow already works well for other language pairs that could be construed as similar to the point of being the same should also be applied here.
