It is similar to the old gopher: text files, links, and images form a hypertext optimized for reading. Text is formatted like Markdown - but even simpler.
Clients display text, like an eBook, or images / media.
Since it does not use "addictive by design" UI elements, like feeds, timelines, likes and upvotes, colorful and distracting elements, endless scrolling, as well as comments that invite trolling, it feels a lot calmer.
Servers can run on a PC or Raspberry Pi which needs half a Watt of power. No FAANG companies needed. No expert knowledge needed - not more difficult than running a file sharing client.
I think it is the right thing for defense of democracy and sharing your voice in the digital realm.
Edit: If you see comments here which kinda miss the point, appeal to emotions, have faulty logic, or depart from entirely incorrect assumptions: Please keep in mind that big US tech companies can't say "that's bad, how will we shovel money with this?". Please use your critical thinking skills - they are much needed here!
Oh, I see I made an error here:
The page I cited gives the power consumption in Ampere, it is 0.360 Ampere.
This is not, and this is what I overlooked, equal to the power consumption in Watt.
What applies here is the formula
where I is current in Ampere, U is Voltage, and P is Power in Watt. And while I is 0.36 Ampere, U is 5.1 Volt (see www.raspberrypi.com/products/power-supply) , so the real power consumption is
1.85 Watt (instead of "half a Watt").
The 5 A charger can deliver 25.5 Watt.
