There is freifunk in Germany they use Mesh Network -> Router > VPN to another Country so they dont get Problems by People pirating.

No, but don't use SMS either. Meta Apps have the permission to access SMS.

LiMux failed because Torvalds didn't bribed the Mayor and the ruling Conservatives, like M$/Gates and Balmer personally did.

There is a big difference tho.

It also allows to communicate with non-delta chat users via email through the same chat interface

That's a disadvantage. Messengers should only allow secure encrypted chats!

Teleguard defenitly not they are closed source.

MMS (Multimedia Messaging Service) is not available anymore in Germany. Why would anyone sane use that shit if there are free options?

Depends currently I use a free one where they are included. Before that I used another one where they were extra and before that I used a prepaid plan where they were extra just data was cheaper.

See my post above: WhatsApp backups are unencrypted by default to Google/Apple servers. But at least you have options to make it more secure.

If you Chat via WhatsApp the Chat is probably in cleartext on the servers of

• Google
• Apple
• Meta
• NSA and stuff

But at least You can be sure if you are really chatting to the right person

You can send self destructive messages with a very short livespan that probably won't land in cleartext on somebody else's devices.

If you call you are Safe, its encrypted and not stored unencrypted in backups.

So its possible to use it encrypted

If you Chat via SMS the Chat is probably in cleartext on the servers of

• Provider1
• Provider2
• Google
• Apple
• Meta
• NSA and stuff
• but also any other Spy agency or snoop that has access to SS7

You can't be sure if you are really chatting to the right person

Calls are interceptable.

impossible to use securely

They are more commonly used and thus have a large community and documentation and packages also from commercial vendors.

Would rather use WhatsApp then SMS. Its much more secure and private and doesn't cost money. Although if RCS is an option it could be used instead of SMS or WhatsApp.
