Yes. I once was using an old laptop for travel and didn’t care if it got lost. It hadn’t been updated years but I got a nasty virus from visiting Spotify once that embedded itself into the tcp/ip stack. Not that I cared much for the laptop but it was a wakeup call that ads contain viruses. I’ve ran adblockers before that incident on my main computers but since it was old I didn’t I have everything up to date. Since then I’ve made sure to install ublock origin on any computer I touch. Even friends and family with their permission.

I could write an essay on why I block ads but the other comments sum it up pretty well.
