android tablet have many way to run a linux user land . but most of them are still using downstream android kernel. which means you wont get any 3d acceleration in your “linux” environment. so i would suggest you some sbc based tablet or some chromebook (then install linux on it manually)

im using cloudflare doh as upstream. and setting my own dns server (dnsmasq) with ad block hosts on my router

you can use netevent. it will expose your tablet input directly to your host computer by uinput

but it just the ec part. bios is still the proprietary insyde bios

to be noticed. framework laptop still dont have coreboot support yet.

adaway is a classic hosts based ad blocker, usually have effect for in app ads. for ad in webpage, i suggest firefox with ubo installed

any lineage os supported device is enough, i think

why not just use email? i think most college student have it. and you already chating on it

exactly. thats why i only use temporary email to register. and use different username on different platform

if you are using btrfs. try btrfs send

gesture navigation is fine for me. but i more want stacking recent tasks back

i suggest to use a open source front end (such as newpipe). and use adayaw (a hosts based ad blocker) for the generic ads

you can use profile manager to do what exactly are you doing. without install multiple version of firefox
