Compound words are very different than agglutinative conjugation though. In such languages, you don't just mash words together, you also modify them to encode all sorts of extra information into one word. You can form full, grammatically correct sentences that way. Can't do that with compound words because you can't compound them into a complete sentence.
A famous, powe example is the word "çekoslovakyalılaştırabildiklerimizdensiniz" from Turkish, which is like Finnish in that regard. It's a complete sentence that means "you are one of those who we have managed to make a czechoslovakian". The object, subject, verb, tense, and more are all in there. Obviously that's quite a bit more complex than word together-mashing.
I use Linux myself, but my work laptop they gave me is windows. I can honestly say that I believe in near future the average Linux experience is going to be smoother than windows. Because I cannot believe how insanely annoying windows 11 is. It's really not good. And modern Linux has more than good enough software and hardware compatibility.
But of course it's gonna take a long while before Linux overtakes windows because social inertia. And that's not gonna change easily because there is no humongous international corporation that spends billions every year to get their Linux based OS pre-installed on almost every new computer.
