There is watomatic which does exactly this. You can select messenger/WhatsApp and when one reply or messages you. It auto responds with whatever text you want.

Thunderbird is very nice and lightweight compared with outlook. Picks up email settings more quicker and is much simpler to use than outlook. Recommended to all my clients.

Especially 3D objects

I did a look into this. softmaker is best when it comes to compatibility of displaying files. Wps office is ok, but some text would be on top of others. I did find that there is a free version of softmaker, which should be ok.

I think it’s worth it.

Just simply send a link along with that’s generally better and that lots of people are moving over. Watomatic could be looked into as a way to automatically remind people you are on signal when they go to Facebook you. It would then prompt then to install signal.

I take the attitude if they want to contact me either, phone, email or text.

I use lucky backup to mirror to external drive. And I also use Duplicacy to back up 2 other separate drives at the same time. Have a read on the data hoarder wiki on backups.

There are none. As its Facebook.

You are better of inviting them to Signal. If they know how to use WhatsApp, then they know how to use Signal. It’s designed to be as easy as possible, while secure and private.

Neither

Overall, use Signal, but telegram has more features than WhatsApp. So much that WhatsApp at this point is just copying telegram.
