Yup, Microsoft has made criticizable choices and i'm pro-Linux, but :

• I would need to document myself on this topic ;
• Conspiracies about his links with covid(, harder to find on the Internet, i remember that they made a simulation for a global coronavirus pandemic ~6 months prior(, here, but there's also a 90-pages long pdf ~~also written at the end of 2019~~ written in 2017, and unrelated to event 201 and whatever conspiracy there may be(, i didn't take a look at these theories), but interesting nonetheless, advising the government for censorship among other things,) among other weird coincidences,) may be partially true for all i know, but in any case he's at worst a co-conspirator and not the instigator(, if he played a role at all, which i still doubt/'don't really believe', contrary to intelligence services who are much more used to biological weapons, perhaps as horrific as atomic ones, and intersideral wars will destroy whole planets if we haven't solved wars until then(, while keeping our diversity since it's desirable&possible)), i'll pass on the dishonesty of "our world in data" since he's following the standard and isn't an exception there(, statista is worse[, edit to clarify on my suspicions on this standard : i was thinking of the number of deaths probably overestimated(, e.g., the flu stopped killing) ; but also of very subjective personal choices like how a growing inequality isn't emphasised here, or relevant indicators to observe neo-colonialism ; or the choice of g.d.p. as an indicator because, e.g., rent inflates it and make it seem as if capitalism produces more g.d.p. ; and mostly overall suspicions towards a certain vision of economy that should perhaps not be considered as the orthodoxy, if only for the numerous negative externalities, the 'lucrative properties'/'passive income', and the lack of democratic control of our workplace, things aren't perfect and experimentations of theoretical improvements should be allowed outside&inside of our borders/control, technologies changed everything, i deny the superiority of capitalism for bringing innovations(, R&D is a waste of money when you can simply copy and focus on communication, our generations are breed in this atmosphere and despite being more wealthy aren't really the child of our past nobles, we had it for centuries and then lost it)]) ;
• His expense of wealth(, even if he's wealthier than when he started donating,) are something i can only clap for. Since it is the only thing i vaguely documented myself on, Bill Gates is among the billionaires who spent their stolen wealth in the best manner, yes, i feel that i can only applaud.

I'd have preferred if citizens, religious, or public organisations filled this role, but they're not powerful enough(, states excluded, and some humanitarian associations, who always lack donations), so i'm glad that some capitalists fight against preventable diseases/deaths in ~~poor~~exploited countries, it could be worse since our "morals" are celebrating the "virtue" of capitalists' selfishness, so double yay for B.Gates, W.Buffet, and other philanthropists, unironically(, because even if it's not ideal it could be worse and their donation/wealth/power is needed).
It seems like an irrefutable point of view to claim that you can rank humans/billionaires according to the virtue of their deeds, and that putting all of them on the same scale is dishonest, just take random examples like the Walton family among others, they're your typical billionaires, others are even worse since they're supporting political/media/educational/.. views increasing the economic inequalities in their favor, or even the so-called "anarcho"-capitalism, we're far from our previous ideals of equality(, social reproduction/determinism : private education, inheritance, ...). So yeah, i unapologetically rejoice that some of them are using their stolen wealth/power for greater causes.
