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.
I will occasionally suggest it if I am doing any kind of tech support but I don’t push it. Occasionally it can cause issues with webpages and if they aren’t savvy enough to have an ad blocker already I don’t know if they would have the knowledge of when to toggle it on and off.
