I suppose you’re asking if I’m French? Yes. And, yes, it’s a French operator (Bouygues Mobile)

Anyone have any advice?

• Ask them for their number, and see how it goes? Worst case, they will say ‘no’, end of the story. Maybe the will ask why you don’t have IG and that will be the start of an interesting conversation.
• Try to meet different kind of people? I mean it seriously. I know a lot of people around me who have IG/Facebook/X and so on but at the same time none of them make it a requirement to use it.
• Use a second phone/number for that crap content only? I barely use my ‘real’ phone (I have nothing installed on it beside what I’m required to use) still I do own a second phone just so I can easily share a number with all the services and various craps that ask for one. It’s a phone I never answer to, despite it being constantly harassed by callers. And that peace of mind (my real number is almost spam free) only costs me the 2€/month (plus the phone, I purchased used). You should be able to do something similar for social networks: have a second phone without anything personal on it, just with IG.
• Accept that you’re doomed to use IG because it’s with those ‘IG people’ and no others you want to spend your time with? I like to spend time with people reading books, it’s kinda expected we indeed read books. Would I not like to read, I would not spend as much time with them.

Neither Tuta or Proton will neatly integrate with Apple Mail if you want to send/receive encrypted messages. At least the last I checked it required for Proton a separate client that was not bug free (can’t remember for tuta).

If you don’t care about encryption, you may want to consider the Swiss Infomaniak.

They have a cloud offer which includes cloud storage (1to base), calendar and email, plus the online version of MSOffice, all being hosted on their Swiss servers.

I may have missed something, here so to make sure:

1. Do you want a wiki specifically, or are you looking for a tool that would allow you to easily create and manage some worldbuilding bible, be it a wiki or not a wiki?
2. Isn’t LibreOffice able to export to MediaWiki (Wikipedia)? I have not checked, and never used it, but I think it’s there somewhere.

the best thing it can do is just make a document look good,

It can also help you write the actual book, worrying about the document ‘look’ aka its formatting is optional (and if done properly, using Styles, it’s almost 100% automated) ;)

Wouldn’t a word processor do trick? you can add links, images, refs, notes,… and have as many pages as you need (edit: and search them, add a table of content, and so on). LIbreOffice is most certainly already installed on your Linux distro and is also available for Mac and Windows.
