Maybe I have mistaken you for a troll, but your behavior and recent posts on this community say otherwise as they are low-effort and look like bait. Asking questions is always a good thing, I don’t want to discourage you from that. Though you should keep the hypothetical, unrealistic ones in your head as they are contributing nothing here and only waste other people’s time.

It seems you are just young and naive judging from your profile picture, so here’s some advice:
Post less, and research/read more before asking anything. It’ll make you grow faster, not only as a developer, but it also teaches you to think things through better and so you can learn things easily in the future. (RTFM anyone?)

Stop feeding the troll…

Do you own an action cam and does it work with Linux?

I have a DJI Action 3. It works with no issues on (Arch) Linux.

What totally rad sport/hobby do you use it for?

I mount it to my helmet while I’m out riding my motorcycle on the streets as sort of a dashcam.

Are you able to update the firmware over Linux or from he device itself? (I have windows for emergencies, but prefer not to use it.

The one thing I hate about the Action 3 is that it requires a mobile app to do firmware updates. Just to start using it requires registration on their DJI Mimo app which is terrible.

How does the device mount and have you had issues with file transfers?

The device lets you choose if it is as a webcam or storage for mounting when turned on if it is plugged in through USB.

Is there any special software that helps you use your device, for example “piper” can help me configure fancy mice.

The Action 3 doesn’t have anything special, but a search on the AUR shows there are some for GoPros.

Can you use your device as a webcam?

Answered above.
