Every US corp is trying to do business in China, including Apple. The ones I have a severe problem with are the ones that literally GIVE their products away to the Chicoms for free. Once the problem of these givaways are resolved, we can work to stop all tech transfers to China, which should be our ultimate goal, so long as they are a totalitarian government. But you aren't making any progress on that until you at least take the baby step of cutting off the transfers that are happening for free, there's literally nothing in that for us, at all.
But Microsoft goes far beyond doing business with them. Bill Gates gives lavish praise and active support to the ChiCom dictatorship - and you give nothing but lip service about it.
