Vaultwarden is pretty nice. I had it set up in minutes and it works perfectly.

Yes. But it is very easy to selfhost yourself (probably what you want in an enterprise setting).

Last time I checked Matrix was researching about the topic of multiple homeservers. So you could just use a local homeserver on your device and a remote homesesrver with a fancy name simultaniously. This would also enable users to communicate P2P. But I don't know how advanced this system is yet.

WhatsApp too…

You can just send your current Location. Not have the message update continuously.

The feature that I missed the most after switching to signal was Live location sharing. It is just so convenient to find your friends while going out or going to the street exactly at the time someone is there to pick you up.

I did. But they probably just replaced the setup cartridges in the backpacks with normal ones. Sadly there are only so many manufacturers who make good quality backpack-sized printers.

Some years ago I was on a Civil Protection Excercise as the IT and Communications Officer. Part of my Gear was a small printer (can't remember which brand). After I set up the laptops for the team I put the cartridges in the printer and the printer told me, that these were the "Setup Cartridges" which were only usable in the first few months after purchase. And that I was supposed to buy normal cartridges to use the printer.

I was able to get a replacement printer from the place where we were staying, but this situation still enrages me to this day. What if this had been a real emergency?
