In order to participate in modern life you have to own a device which is able to connect to the internet. Also older devices get often gifted away to those who can less afford them.
At least on Android you have NewPipe, which is an easy to install alternative Frontend for YouTube, or YouTube ReVanced, which applies multiple Patches to the original YouTube-App in order to make it more useable, however sometime the patching process causes trouble.
I’m currently using Revanced and it still works like a charm and completly adfree.
