I am curious if the fact that a lot people use pop os on hardware other than system76 hardware is detrimental or helpful towards the development of the OS and the workload of the devs. Like if the number of users of pop os on different hardware configs increases, is that helpful for the devs considering that it may increase the number of bugs and hence result in an increase in worload
I am no expert, but it feels like it just requires the work of low-level softwares, like kernel, systemd, drivers. At the distro level (ignoring hardware focused distro like Asahi), it should be mostly hardware agnostic. This is why most linux distro supports all hardware.
Using these distro provides valuable diagnostic data (assume you turn it on) to make popos or linux in general better.
So I would think it is likely a relatively positive thing to use popos if you like them.
