Decentralizr

Own server is always the most private, but you can use any instance and should be fine. Its e2ee, so you should have a way better setup as with slack or Microsoft

Yes matrix has that, rooms and also spaces

Matrix has channels. Or what are you referring to? I did nor use slack since many years

I would say elementary is easy for new users? What did I miss haha. This said I go with fedora or popos for new users.

Matrix or Jitsi when it comes to privacy. Microsoft vs. Slack is the totally wrong approach when it comes to privacy.

Looks interesting, yet not open source? What is a d-payment? Some own coin stuff or erc20? Anyhow, I never used any of the two, and I wonder why we need more?

Sadly a lot of proton promises are super delayed or never happen. Android still relies on Google services for push.. even it was promised 3 years back to release a version that won't relay on Google.

I tried monero.town, lemmy.ml and 3 others and had the same problem.

No I think some instances are not allowing others to be found. I tried 3 others and can't find particl if I search. I find it only on lemmy.world when I search. If I search on lemmy.ee for example, I can find monero, but not particl. Or privacy etc... particl is only found when you search on lemmy.world

Can't find this particl setup from other instances when I search. Is that normal? Or can it be fixed?

This instance seems to have a lot of downtime and is not connected to other instances. Tried to connect from monero.town or lemm.ee and can't find the particl link here. Can we mirror or move to a connected instance? I am happy to help. PS tried to send this via internal message, and this also keeps failing.

Jitsi, perhaps matrix (element), signal (has tell number) works too. Threema also added video into it.. and an unpopular one brave (has it without signing in, within the browser)
