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.
Pihole was the best thing I ever set up for home Internet consumption
Add on a OpenVPN instance to keep mobile devices behind that pihole when on mobile data/external wifi.
Plus a little extra encryption across public networks couldn’t hurt.
