Because I prefer a seperate client instead of every messaging protocol to rely on a browser or Electron. Because it's faster to have it auto-open on desktop than to log in (with 2FA) via a browser every time I reboot. Because I like having a local copy of my email. Because it's more pleasant to use multiple accounts with a single, consistant UI. Because I have money for more RAM and compute, but Thunderbird (or other clients) are typically lighter in my experience, so I'll use my RAM or cash for something else.
