It's less about getting away with not paying taxes and more about the fact that RSUs are basically a big negative-interest loan to invest in the company's stock, which can be incredibly lucrative in the growth sector.
I would actually like RSUs more if they granted me shares in a basket of stocks of competitor companies. At least then it would hedge my already high exposure to the fortunes of the company I work for.
I am not seeing where the positive interest is here.
