I already listed my reasons for wanting to try out/use it, and they have nothing to do with crypto or micropayments.

If you can name alternatives with similar functionality made by people who are not affiliated with crypto, I’m all ears. Briar seems great for journalists and activists etc, but it is too limited to be used as a mainstream messenger for keeping in touch with friends and family. Seems like all you can do is send text and emojis, no video chat or photos.

I’m no crypto fan or plan on using micropayments either, but if I don’t use it, where’s the harm?

And National Libraries and similar institutions around the world, for example https://www.nb.no/en/digital-preservation/
