I use a 6 year old desktop which wasn't that great even when I built it, and a pretty terrible 8 year old laptop, and I don't have any problems with uBlock Origin's performance. I have almost every filter list enabled (except for some regional ones), which results in 153486 network and 173646 cosmetic filters total.
What are you talking about? uBlock Origin is not tied to Chromium, and is not controlled by Google (unlike Brave which is just a fork of Chromium).
Jesus, why does everyone these days automatically assumes that everyone else is using Chrome or Chromium? It's almost as crazy as calling Windows a "PC".
Google controls the frontend APIs uBlock origin is allowed to use, and they have pushed changes numerous times in the past (covered on HN) to intentionally nerf uBlock origin because it hurts their bottom line.
