Those companies have R&D for a reason. A company _wants_ to make things, right? If this is impacting their ability to make things, wouldn't it be in a company's best interest to advocate openly against the tax code, rather than be silent about the reason, fire their staff, and just not make things?
It doesn't make sense to me how so many people are aware of this to the point that many many companies are all doing the same thing for the same reason, but seemingly nobody was talking about it before this post. That doesn't make a lot of sense to me.
