What?

I love Wireshark but I hate every day I have to open it up :D

(any Flatpak user would’ve at some point run into annoying sandboxing limitations - such as password manager and browser integration, or themeing woes)

While I overall do prefer Flatpak over AppImage these days, the sandboxing has indeed been giving me more trouble than I think it is worth so far.

it’s really good if you have a fairly new machine

It’s running well on my 2013 laptop as well.

OpenSUSE Tumbleweed on my desktop and laptop. On my desktop mainly due to newest drivers. I had bought a very new AMD GPU at the time and Tumbleweed was one of the first distros to support it. Switched my laptop to it because of familiarity.
I started my IT career on Debian servers and so my private servers are on Debian too. They were on OpenSUSE Leap for a while but I switched when the future of Leap became a bit uncertain.

If this defaults to off, I’m turning it on.

I’m not aware of any distro that automatically clears a user’s .cache in their home directories. Maybe you’re thinking of /var/cache?

Personally I’ve been happy with the Nokia branded phones (manufactured by HMD Global).

I saved many many documents as pdf via libre office and never encountered this feature, so I’d say so too.

I recently contributed a business change and got a message a few hours later that I had made a mistake and a small explanation on how to fix it.

This probably depends on the area, but at least changes in my area seem to be monitored by good people.
