This is a good a start as any to market Linux to the common end-user. It's not about the software being better; it's about the software offering the user some advantage, like not needing to buy new hardware.
Linux is, far from perfect still. It has a metric ton of "foot guns" that cannot be pointed anywhere away from the feet; the user MUST move their feet away to avoid these "foot guns". It has a lot of pain points and still lacks polish in some ways. Most things mostly just work; but may the gods and goddesses help you if something for some reason does not work, or does not work as expected for any reason. Coaxing it to work exactly as expected might seem impossible for average users.
Then there's the issue of Linux having only volunteer support in most cases. Getting help from an overworked and under-interested FLOSS developer is like pulling teeth; even when they're literally the only person on the planet who can solve your problem
That being said; Linux is free and mostly usable. 9/10 times it does work and can save you a lot of hassle and headache if all your computing needs are basic and predictable.
