Oh, you. Thinking uBlock Origin actually blocks advertising. It doesn't block sponsored blog posts, sponsored comments, paid reviews, conflicts of interest, marketing copy on landing pages, etc. Advertising is everywhere.

And uBlock can't protect you from anything not in your web browser.

I don't think I use any proprietary web services outside of either my web browser (90%) or command-line CURL (10%).

I have 3 PC game platforms, Discord's desktop client, 4 cloud services, and probably some company hubs for drivers (Nvidia, Logitech, Razer, etc) that phone home. You can definitely access all these through a browser intermediary, but many don't. Steam sort of needs to stay on your device for DRM purposes anyway.

What? You mean it doesn't block billboards or radio ads either? It doesn't block my friends when they start talking about their iPhones or being Vegan?

There's just no avoiding those astroturfed marketing campaigns being pushed by Big Vegan.

Minimalism is a scam created by by big small to sell more less.
