LTT also did videos about PiHole and YouTube Vanced, so I personally don't think it's hypocrisy advertising VPN's (as long as those VPN ads don't lie about it's benefits).

I do believe that Linus once again uses words in ways not commonly used. I.e. if they define piracy as

consuming content without paying how the creator intended

then blcoking ads is piracy. But the commonly used definition is more like wikipedia's

[...] Online piracy or software piracy is the practice of downloading and distributing copyrighted works digitally without permission [...]
