Please correct me if I am wrong.

What grinds my gears about email monopoly is that you cannot create or integrate easily email client now.

To access mail it is not enough to provide user & password & whatever. Things can provide access without compromising security.

To access gmail? User needs to add access from some bullshit console settings, and stuff. I asked chatgpt how thunderbird is not required to do this, and it said that it has keys pregenerated, and big corpos can operate like that. I have not verified that any longer. Sounded credible. So annoying
