It's not 'every problem'. People know Windows. People understand most of Windows. They took years to do so, and they still run into problems. Now you ask them 'switch over to Linux, it doesn't have problem X', without understanding the average person doesn't want to invest the time or effort learning anything more complicated than downloading and installing a random .exe (why do you think phishing and malware are so prevalent in their infantile state?).

This is reinforced by most major apps which eventually become cross-platform starting out treating Linux as a 3rd class citizen. For games, Discord and Parsec come to mind, where the former took years, and the latter still doesn't allow hosting from Linux. Nothing about this reinforces the idea of Linux being easier to use. It's the opposite: it reinforces the mentality that Linux is still two decades behind, regardless what the reality may be.

How many complaints form when YouTube pushes a minor UI or UX change? Now multiply that by a few magnitudes of order. That is the problem we're dealing with, and no amount of chastising or belittling Windows users will change that (in fact, it does the opposite). Did people forget how Apple managed to get a foothold in the market despite their ludicrous prices and dev-unfriendly practices?
