I use ad blockers and open source privacy focused software whenever I can but occasionally I have to use computers that don’t belong to me or an older phone where my usual applications aren’t installed and seeing all the advertisements just feels dirty and dystopian.
I think the worst ads are the text to speech ones that say “Download this app today”. The unblinking energenic people saying you can make a living at home are probably a close second.
You’re pretty much gonna have to switch browsers. There are other options, but they don’t work as well as uBlock Origin. The best alternative to that is a VPN that blocks ads, like Proton. But they aren’t as good at blocking. They will, however, remove most ads, and from other apps as well.
