Simplifiedprivacy dot com needs to be blacklisted from Lemmy communities, it’s a blog trying to sell some really silly services.
As for Session, they’ve never made an original product that I’ve ever seen - they took Signal and Monero, peeled off the labels, and made them (especially Signal, IMO) worse in both aesthetics and privacy protection.
And the company behind this is in Australia, a country where you need to weaken products (by adding backdoors) upon government request.
