It's just like if you tell someone a joke. You can still claim credit for coming up with it, but not to stop its propagation.
In particular, you can still make money as a developer by asking for it upfront, whether from an employer, or patrons, or early access, or whatever model. Similar to how Netflix might pay someone upfront to develop a stand-up comedy special
That said, I basically never seen anyone charge for a distribution. I figured that people think there's no point, so they just don't.
Now, charging for development? That absolutely happens.
I charge for development of (F)OSS. It's my salary. My employer likewise charges the patrons/funding agencies. But we get paid once for the effort, like any usual labor contract. We don't try to get paid again when our past work products are copied.
In the old days, paying a distribution cost was more common for free software, when it actually took effort such as writing and shipping media. This handled the case where someone asked for a distribution, so that sharing did not become a financial burden. It's a mostly obsolete concept now with pervasive internet and many low cost or free hosting options to put content out there at essentially zero marginal cost to deliver copies.
Huh? Finder is the macos equivalent of explorer.exe and it's the GUI for the file system. I assume you're taking about Spotlight which searches the entire file system and the internet much like the Windows start menu.
Anyway people have been making claims like this for as long as computers have been around. Smart people use Spotlight and the start menu because it requires fewer keystrokes than typing full paths or clicking 10 times to navigate a directory tree with Finder. It would be stupid to avoid using the fastest tools available
Ultimately, some people are just not interested in technology or using it efficiently.

I definitely agree that the general trend towards less advanced technology will harm that though (some 18yo's don't even know how files work because they just use Mac's Finder), but some cohort of the generation will _always_ be interested in digging deeper.
It perhaps doesn't help that the general attitude of someone in FOSS/tech in general could be perceived by the average person as elitist or exclusionary - I try my hardest to challenge these notions.
