Desktop linux has a ways to go before it's ready for "normal" users.
Yes, yes, yes, you have a story about how your parents (sibling|partner|friend|etc) are using linux and don't even notice/care. They have you directly supporting them and I'll call you a liar if you say you've never had to support them. Even if it's just "Netflix won't stream high quality to me". Even in our browser-based world you still often need to install some software and good luck explaining why they can't run Photoshop or MS Office.
All of the reasons listed here simply don't matter to the vast majority of the target audience.
Linux is amazing, I use it every day, I'm surrounded by machines running it in my personal and professional life, but this seems misguided. A bunch of us nerds can cheer it on but people who you are trying to target aren't going to be interested.
This is awesome! I'm not sure how well it will work, but it's a very noble effort
