They aren't just a tech company though are they? They are one of the largest companies in the world with an annual turnover comparable with small countries like Denmark or Norway.
That is true but they aren’t a country. They don’t set international policy. They have little to gain and a lot to lose picking this battle.
For one thing they have close business relationships with people in both china and Taiwan. They have employees in both countries. Vendors. Human relationships. Those might get kinda awkward if they picked this battle.
And what do they gain picking this battle? A few internet points?
