I think this is why google really wants to control the brower. Once AI is cheap and on every device, the user has the ability to use it to filter all inbound. Trivial for a local LLM to strip hate speech from a twitter html regardless how much Elon wants you to force you to see it.
Most people don't even use an adblocker, despite how easy it is. I think you will have a hard time trying to get a substantial number of people to install a filter for opinions you/they don't like.
You may want to actually look at the adblock usage. It’s massive unless artificially disabled. Enough for Facebook and Youtube to fight it with escalating countermeasures
