If you're afraid to or don't want to pay for software then you should probably use some variant of GNU/Linux instead.
Frankly this mindset is ludicrous to me and yet I see this with MacOS users too who happily pay for third party solutions to first-party breakage on stuff you already paid for. Somehow the more you spend the less customizable software is and the even more you have to spend to work around dumb choices.
I'm going against the mindset of not paying for software in general, no matter how useful it is to you.
For me personally, I'm more than happy to pay for software if it's clear the developer has _my_ interests in mind when building it (think IDEs, CAD software, even stuff like Office or the Adobe suite). I'm also OK with using software that's free and dealing with dark patterns (shareware, online tools) or bugs (open source stuff).
But paid software that somehow still tries to bilk me for even more money? (See all of the ads that have been built into Windows these days, or various Android phones and bloat) I will be more than happy to go out of my way to crack and get out of paying for it, for nothing but to spite developers of such things. You can't have your cake and eat it too!
I think the parent was assuming only legal options.
If that's not a constraint, then food, cars, etc. are also free.
Also, taking someone's car or food deprives them of them. Making a copy of Windows doesn't make it impossible for Microsoft to keep selling it.
I only use it to mean illegal copying.
I think his use of the term "pirate" was confusing.
