Bandcamp, Supraph Online, Ototoy, Uta 573, Steam and GOG’s OSTs and Apple’s iTunes store have been my to-go options. No DRM, no worries. Just avoid Apple’s music subscription, as it is DRM’d.

Iirc, there are unofficial ports of LineageOS for newer devices. Also, I've been using another system, ArrowOS, in its vanilla form, on a Redmi Note 10 Pro phone I have, and it's working fine so far, so maybe an alternative for your case if you don't find a decent phone compatible with LineageOS?

Yes. ( also just remembered there are some mix up in naming conventions across the fediverse… "<.< )

Just checked your instance, and this page seems like a good start:
https://lemm.ee/communities?listingType=All&page=1

Then you can filter pages around, subscribe to pages as they pick your interest, etc.

Then, if it’s anything like Lemmy World about sorting (can’t verify since I don’t have an account in your instance), you can visit https://lemm.ee/?dataType=Post&listingType=Subscribed&page=1&sort=New to check all your subscribed contents, and by newest (I recommend “newest” because I get the impression posts start repeating themselves after a while with other sorting features).

I’d suggest Linux Mint.

• Simple UI
• (Xfce version specifically) is very fast (within reason; it’s still a modern OS)
• It’s already pretty keyboard-centric and it can be improved further if you like tinkering (my reason for dropping Windows was precisely lack of keyboard-centric controls, so if I stick to Mint, I guess it’s good on that front)
• Keys can be custom mapped, although I guess most bigger Linux systems allow that either out of the box, or through 3rd party software
• Unsure what a “dotfile” is, so can’t comment on that
• And Mint is still slowly adding animations to its functions (to some people’s dismay), and I don’t feel lag when alt-tabbing around, so I guess it is snappy too

If I may suggest, start following federated pages too. Each social media has its niche, and now, with federation that allows direct communications, it’s the perfect opportunity to find a social media whose features you like (which you seem to have already gotten), and curate your contents so it’s perfect for you without depending solely on your chosen social media’s niche.

Besides, Windows can be very laggy even on supported hardware.

Looking for a more stable distro could be a good idea. Some distros are pretty much only PoC, or too niche to have a good support, or the beta channel of another, better supported distro.

Brazil does, but while such a set laws exist, seeing those laws being enforced is a distant dream.

One problem is that you don’t know who’s actually hoarding your data and for what purpose.
