Can we have the names in the headlines of which MPs keeps consistently putting this crap on the agenda multiple times every year for the last couple of decades?
You say this but Matrix is largely centralized so it would be easy to get the biggest node to comply. Servers are quite costly to run too which is a big problem.
I don't think Startmail will be affected. Ofcourse using Gmail is free pass to your data. But look at this https://www.startmail.com/ . I think if you also use Proton or other mailing services you're 99,9% safe. I sometimes play video games, some of my friends are kids who are cursing in gamechats. How will gaming chats be affected? Does the government have access already?
The americans seem to have figured out how to get change in relation to health insurance. Perhaps people might consider taking a page from the french history books to get some change on this issue.
The same French of whom more than a third want an authoritarian strongman in power? Personally I would prefer to copy the handful of boring countries where people actually trust their leaders and so don't feel they need to resort to bloody revolution at the drop of a hat.
Why are they still thinking they can justify this? People which do illegal stuff are just going to use old apps self-host or bypass it with another way.
Edit: At least it is if both the sender and recripient uses protonmail. Its open source so you could verify the client to make sure that the contents are encrypted. As for IP address and subject lines tho, that's up to the Protonmail company to honor your privacy, and just hope they don't betray you.
Of course there are alternatives. That's the cherry on top of this crap pile: only regular non tech folks are affected. Nerds and actual criminals will just run an xmpp or simplex server and not care about the legislation.
