With Headscale being an open source, self-hosted implementation of the Tailscale control server.

Screw communities, i just wanna influence everywhere... great.

Apparently so... couldn't be bothered with an account to go check...

isn’t IPv6 going to somehow mitigate that issue?

AFAIK all IPv6 does is ensuring everybody and their dog gets a publicly addressable IP address, plus encryption, but i'm far from an expert.

The self-hosting email frustration arises from years of cartelization under the "it's to prevent spam" banner (if it was to backdoor encrypted apps they'd go with "think of the children").

Like something like I2P?

I think I2P is an overlay layer, i haven't delved into that... i assume it would require that the recipient was on I2P as well. So impractical, to say the least.

Do you have any clue where or how we can join a community/group that somehow fights back those kind of unfair and monopoly behavior of big tech companies ?

It's a David vs Goliath thing... the EFF does some interesting stuff, maybe they have something of interest to you. Then there's politicians if a) they actually represent you and b) can grasp the concepts.

Tailscale

Have you considered Headscale?

What's your mail stack and your take on self-hosting dying?

Depends on your threat modeling.

I have an address to register in irrelevant sites and the provider is also irrelevant.

I have an address for important use (utilities' bills, government stuff, friends), currently tuta.

I also have an alias there for occasional registrations.

I'd try proton (has an .onion site) but they force you to supply a phone number or email address on registration, which for me defeats the purpose. They also leak a lot of links to clearnet.

Self-hosting has become increasingly hard but I haven't tried it.

due to deployment hell you end up using docker

Maybe tackle that deployment hell instead of band-aiding it with docker?

The comment section mentions that conundrum as well... quite interesting.

The comment thread in that article is interesting. Grep for Ada.

OF course they're more prone to blackouts, and what the study says is that they're less likely to cause severe blackouts than traditional power systems, because they're distributed so that reduces the likeliness; and grids rely on other systems as baseline anyway.

DNS, most web searches, trackers in apps, location data, just to name a few. Ad blockers won't help you there.
