The people who wanted A created B. It's not really a conflation but more of a causal reality.

Yes but the headwinds of Linux adoption are (to some extent) that Linux is the best choice for A, but it is not far and away the best choice for B (not saying it’s bad or even worse than Windows, it’s just not CLEARLY better).

But when you approach 99% of the population who, to the extent they’ve even thought about it, will only judge an OS on B, Linux is just one of 3 main choices (sorry BSD folks. Don’t yell at me). Is it the best choice purely on functionality and app ecosystem? Maybe, but also maybe not.

Since the majority of Linux does not come on hardware by default what you’re essentially asking people to do is to buy a car and swap out the motor. We have to convince them why that new motor is better and is worth the effort of doing so. If it’s marginally better or worse, it just won’t be worth the headache to most people.

To be clear Linux (and MacOS) are my preferred OS. I haven’t owned a Windows box in at least 5 years.
