I’ve not used it for quite a bit, but look at Thunderbird (a mozilla project iirc), it might do what you want as far as email is concerned. However do note that Microsoft is really closing things down in outlook/office these days, they really don’t like people using a “real” Linux (they want people to use windows with all their crap and start menu ads, and just have a small Linux VM they call the wsl )

The massive influx of new ratings could also simply be linked to the fact that the game is included in this month’s humble choice, adding a ton of new players

It is also a huge deal because since (at least in France) the government forced ISPs to log DNS queries, a lot of browsers (and latest android and iOSversion’s) have now migrated to DNS over https or TLS DNS, which means that the only clear text DNS query they can intercept is the one to fetch your secure DNS service address. Now, having a trusted CA installed in browsers means that they can also spoof the identity of this secure name service, and regain a bit of control.

They invested a lot in surveillance technology (for both good and bad reasons), and https, DNS and encrypted messaging / phone calls means this was all for nothing.

And yes, by being authorized as a trusted CA, you can effectively spoof pretty much anything by setting a proxy. Some tools even leverage this for app analysis. Look up mitmproxy for example, or squid. A lot of companies already do this to inspect inbound / outbound traffic.
