I'm on mobile data nearly 100% of the time most months. 14GB costs me $50-$70 (depending on which network I'm on, I have two) to download ("unlimited" plans actually aren't, when used as a hotspot, though T-Mobile now seems to actually have a mostly unlimited hotspot option, I haven't tried it yet). So, not only are ads intrusive, disrespectful of privacy, and generally of negative utility for me as a user...they're also ridiculously costly.
So, yeah, I use an ad blocker. Oddly, I tried disabling it earlier today for an LA Times article (because of their blocker blocker), but it didn't correctly detect that I'd disabled it, so I closed it and went elsewhere. Now I know I should never disable ad block for LA Times, no matter how interesting the story seems.
