If we can count FOSS modifications of proprietary apps:
YouTube Revanced (the official YouTube app, but you don't get ads, you can play videos in the background, you get SponsorBlock, etc.) (follow this guide for auto-updates)
Vesktop (desktop client for Discord, has Vencord preinstalled and supports Linux screen sharing)
Prism Launcher (Minecraft: Java Edition launcher that allows you to easily manage different "instances" of the game. Good for playing with different mods and/or versions)
Fabulously Optimized (modpack for Minecraft: Java Edition, that improves performance and adds some minor QoL features)
addendum: I'd like to use Matrix (via the Element client) and Signal more, but most of the people I know are on Discord and WhatsApp instead.
From my experience, accounts that are made with a VPN are shadowbanned. Using pre-existing accounts with some significant activity will be fine though.
Not me unfortunately ... I used to have a Samsung Galaxy S9+ with an unofficial port of LineageOS. Nowadays I'm using a Samsung Galaxy S21 Ultra with the stock OS.
Maybe a Pixel should be my next phone, so that I get proper support for most custom ROMs.
Same in Pakistan. People tend to use a lot of English words in Urdu, even when an equivalent native word exists. For example, the proper way to say "What's the time?" is "کیا وقت ہوا ہے؟" ("kiya waqat hawa hay?"). But a lot of people will say "کیا ٹائم ہے؟" ("kiya time hay?") instead. But of course, there are also loanwords such as "واشنگ مشین" (washing machine) and "کمپیوٹر" (computer).
Never heard of Zen, I'm just using vanilla Firefox on my Linux laptop. Will check it out later :)
