I get the sentiment, and it's not a black and white (sorry for the pun) answer I think. And yes, celebrating your culture should be good for everyone.

Unfortunately, some people saying "pride" mean "There are great things in the culture and people where I emigrated from" and some people mean "the culture and people where you emigrated from are trash". And "white pride" has historically been used by people meaning the latter.

Pointing out that "white pride" COULD also mean the former doesn't remove the implication it comes with for the latter. If I wanted to express the former, I would pick different words. A person doing otherwise usually either expresses ignorance, callousness to the second implication, or them just trying to get away with saying it meaning the second thing by hiding behind the first.

My view is that it incentiveses exclusives in the PC space, as opposed to lowering Steam's charge for their services. My biggest concern for gaming is that we end up just like streaming services. A bunch of exclusives and a marketplace that is such a mess you can barely find what service has what you want.
