The author is an idiot.
When someone comes to me asking how to get into Linux, they do not need to hear a laundry list of distributions to choose from.
Only techies ask anyone how they "get into Linux". Say it with me now. "People don't buy, buy into, get into, install, or use operating systems" They buy fuckin computers. It is perceptibly to virtually all non-techies a feature of the device.
There are a million types of cars but people manage to pick one and buy it same with breakfast cereals or shampoo because they are obligated to make a decision or go hungry, dirty, or walk everywhere.
People don't particularly like making decisions and they decided what OS they were going to use when they bought the computer and they have no intention of downloading an iso, write it to a USB, figure out how they boot from it, figure out the bios options they need to disable and what works differently than what they are familiar with.
You lost them around step 2 and lost all hope of moving forward unless the prize at the end is something much better than "does everything I used to do but differently"
The success of Chromebooks, android phones, and the steam deck is that it was driven by devices people wanted to use not an OS people wanted to use. If you want to see more Linux use that is the story you need to focus on.
