I think it is naïve to assume that your product and vision would replace the existing commercial products and law enforcement strategies. IMHO, it is more likely this will simply end up existing alongside the stuff the exists today and what that means is that less powerful people and organizations now will also have access to this technology and will now be able to abuse it for a variety of motivations and agendas alongside the powerful organizations that are already abusing it (to some degree) today. In other words, IMO proliferation of this technology is not going to end up being anywhere close to a net positive.
I have had a very bad experience with Mailfence where emails from well-known domains do not arrive (no, not even in spam) and I never got any response from their support when I asked for their assistance to receive 2FA codes that I needed. Also, Indeed emails consistently show up in the spam folder, no matter how many times I mark them “not a spam”. Sure, I may not be a paying customer but why offer a free tier if you cannot provide a reliable service? This has caused problems for me and if I had known beforehand I would have went somewhere else.
