It’s literally what you type in terminal to use it

I agree to an extent, but names are hard. I was able to sort of guess what fwupd does without having to read more into it. If it was named “Firmware Updater” I would immediately start asking questions. “Which company made this to update their firmware? Is it safe? Is it a virus?”. The name “fwupd” indicates to me that it’s more of a universal tool (I could be wrong, as I haven’t looked into it) made by the open source community.

I think a solid solution would be for mainstream distrobutions (Linux Mint, Ubuntu, etc.) to maybe have a default wrapper for stuff like this. They could call it whatever they like (“Hardware Updater” or whatever), but it’ll use fwupd for the heavy lifting. Win win.
