M$ has a right to persue violations of copyright/EULA against any of its customers/users. Like any wounded beast lashing out in its death-throes, M$, instead of pursuing violators wants to pursue the customers of violators. The fallout could mean that “the tax” which we now can avoid by buying devices with non-M$ software or building from parts will now be a burden applied to every business which may anywhere use that other OS.
M$ is pushing legislation providing legal liability for any business presumed to use M$’s software illegally. The only real defence against this is to never use M$’s software. I recommend businesses use GNU/Linux. It works for them and not a failing corporation.
M$ has claimed that 90% of the use of their software in China is illegal. China is one of the world’s largest trading partners. Almost every business in the USA uses one or more products made in China. This is about M$ v World. Every Chinese business and every other business trading with China is liable to be hounded by M$’s abuse of the legal system.
