That's like saying the SW ruining on your car's entertainment unit is free. Sure, that SW didn't cost you anything extra, but you paid for it through the car's purchase price.
The innovation has been to install vendor garbage in addition to Microsoft garbage. So it takes even more effort to get a clean system.
Only in the last few years has some distro of Linux started being an option.
And you know what they always say about time: Time is money.
On Linux, I have to tinker with it before I can get shit done with it. It's not optional.
$100~200 USD spent on a Windows license, or $0 by either not activating or using an old 7/8/8.1/10 license, is cheaper than the time-converted-to-money spent on Linux.
That works, unless Windows decides it needs to do a Windows Update before it'll finish booting. Sometimes, which can last several hours. :(
Saying that because one of my close friends was beside himself after staying up all night to get some paper written, ready for submission... only to be screwed over by Windows Update then pulling this shit on him.
Moved him to Linux after that :), though his new job then provided him with a Windows laptop (very locked down) that he's forced to use. And which the MS applications on it keep crashing on a lot (several times a day). :(
It's still far less time (read: money) wasted than needing to tinker with Linux, though. Gods know how much of my life I've wasted there...
Mainly due to my having better things to do in a day than screw with OS settings. With these stable distro's, it tends to be a case of "set the thing once, don't need to touch it again for years". Works for me anyway. :)
