Technology

I am unfortunately not very tech-savvy(I’m better at it than my parents lol but that’s not saying much) but I would like to know more(just a bit at a time, not like my friends in middle school who built their own PCs which is apparently kinda common among tech/gaming hobbyists with a bit of money but I was absolutely blown away). When I was in HS, there was the whole Ajit Pai thing and talk about Net Neutrality. It quickly blew over and people didn’t talk about it much. Basically TL;DR What is it? How does it differentiate from not having net neutrality and what are Marxist opinions on it?
