Some undoubtedly will.

Installing a new browser is already a bit hard for most people. I think you are a little skewed in your thinking being online on HN.

You also aren't thinking about age. Certainly 16 and 18 year old probably can get a new browser installed. But a 14 year old? 12 year old? 10 year old? That barrier is a lot higher the younger a kid is.

I just finished my second year as a fifth grade teacher, so I have a lot of experience with ten year olds. I am confident a majority of my students would be able to install an alternative web browser if they needed to, and a majority of the remainder would ask a friend to do it.

To give you an example of the workarounds kids will find: Youtube was blocked on school laptops, so the kids all started embedding Youtube videos inside of Google Sheets in order to watch stuff. This isn't, like, something a few savvy kids did, it was a widespread and common practice.

Lol. I started building computers, installing operating systems and tinkering with Linux between ages 10-12. I also started watching porn not long after that, and guess what, I still became a more or less normal adult. There is absolutely no need to "protect the children."
