That particular statement wasn’t directed at Grayox specifically, it was more about a particular subset self-identified communists on the internet, including (some of?) the lemmy.ml admins, and many users of lemmygrad and hexbear. The ones that correctly identify that the USA is bad, but then prop up the likes of the Soviet Union, the PRC, the DPRK, and even Russia (which doesn’t even claim to be communist) as paragons of good, when often times they’re worse than the US.
I would argue that all companies are bad. But Microsoft specifically abuses their de facto monopoly to engage in gross invasion of their users’ privacy, and continues to try to wrest their users’ control of their system from them by altering system settings after updates, and making some settings nearly impossible to change. And that’s to say nothing of MS’s attempts to turn their operating system into and advertising platform.
