100% agree. The computer I have now, I only bought because I needed more cores and ram for my docker dev environment. But I had a Yoga 2 Pro. It worked great and was fast for most of what I needed. I gave the machine to my cousin so he could learn to program on it. Still a fast machine. Doesn’t play video games, but it didn’t play video games when I bought it either.
That doesn’t stop any of them. Windows users still go, willy nilly, traipsing around the internet downloading and installing random things. There is no money, no checks and balances. I’m sure you’ve read Windows converts complaining, “Linux isn’t ready for the average user because it’s too hard to install programs, they want to be able to download an installer, then click next next next and have the application installed.” They think the security of package management is too much for the average user.
Sure, FOSS could get some bad actors. It would be no different than the closed source community. At least with FOSS, there is still opportunity for people to find and eliminate the bad code. The world runs on Linux and FOSS. The place where you would want to sneak in some bad code the most. You’d have a much bigger impact. And, it does happen on occasion, people notice, and the bad code is removed. Compare that to the much smaller, Windows world, where you need anti-virus checkers and maleware checkers.
It sounds like you have the computing world inverted. You believe Windows and closed source is the most dominant computing paradigm. It’s not.
