Pewdiepie becoming an arch-pilled rice-maxxer who advocates Linux for freedom and gaming has surely had some effect. He's such a good sport he even swore off Photoshop and tries to learn to like Gimp.
So yeah Pewdiepie is part of it, but I honestly think that's only because Microsoft has done such a poor job at maintaining their operating system.
I have been a linux user for work for a decade, but still ran Windows for a gaming PC. But with Win11 dropping the ball so hard, and the general hype around Proton and where linux gaming was it, it was not hard to make the decision to switch.
I haven't regretted it a single bit.
Granted, I have SponsorBlock installed, so the occasional predatory supplement stuff gets cut, but he also kinda made clear he's rich enough and not in it for the money anymore - and I tend to believe him. PewDiePie won life, chose sanity and took the anti-corruption path. Bless him and his family, and God please, let it be real!
grafx2 provides a decent alternative
Correction: GIMP is annoying/difficult to learn well, but not nearly as bad as Photoshop because it is organized logically and isn't burdened with sacred historical cruft, advertisements and product tie-ins.
The difference is that once you learn Photoshop it is a skill you can use at many jobs, and GIMP is not. Using this post as an excuse to rant, I've always thought that GIMP's priorities should be to be usable for print (mainly color management, which I think is almost totally fixed and becoming smooth) and to improve compatibility between it and vector drawing software (like Illustrator/Inkscape[0]), and layout software (like InDesign/Scribus[1].)[2]
If you're a European government or an individual rich person and you are really serious about software independence from the US, or if you're China/Russia/etc. and we know you're serious about it, you should throw about 50M at the problem. I think it would threaten Adobe so much that the US might lob a missile at you.

[0] Inkscape also hated print, and the possibility of real exact colors and real exact measurements, and basically prioritized web icons and art. They also have a UI that requires a ton of memorization of hotkeys (which was part of the motivation for creating the software in the first place.) They seem to have wised up and made serious improvements in all of those areas.
[1] The only problem that Scribus has is a clunky UI that requires a lot of unnecessary clicks, which makes me suspect that it has deeper architectural problems. I think very few people work on it. It's ideally positioned, in the age of all books being online data, to create/become the future typesetting standard for people who want definitive versions of books rather than flowy ebook things which are not a significant improvement over .txt files. You could take a classic book and encode its typesetting, and rather than having 10M of blurry page scans combined with OCR info, you could just have 500K of text, fonts and typesetting information. With this, you could professionally print a perfect copy of the book, and as it looked when it was printed originally.
[2] Inkscape and Scribus, in turn, should be concentrating on pdf compatability, and also a way to sneak into print shops would be to write a good FOSS imposer (https://en.wikipedia.org/wiki/Imposition) that integrated well with Inkscape/Scribus.
