Bit harsh your opinion touched a nerve apparently to get downvoted. I think you expressed yourself politely and sincerely and you may also be right. Reddit had years to cultivate subs by and for people who are not terminally online, and those are the people who will be slowest to adopt complicated fediverse tech.
I love cars, especially the old restored ones, or reading about people tinkering and troubleshooting. But I subscribe to fuckcars because I fucken hate literal vans being used in my city and clogging up the streets designed for less and smaller traffic. Those Chelsea tractors, as they call them in the UK can fuck right off. Fine em, tax em, whatever you need to do, sabotage their tyres, whatever. Fuck em.
