I don't have any numbers to prove it, but I'd say the reason Linux users aren't freaking out is because the vast majority of them would've have disabled Secure Boot. In fact, many guides and videos from popular Youtubers[1] explicitly state to disable Secure Boot.

As for VMs, whilst the problem indeed affects them too, the reality is that most hypervisors - even commercial ones - don't actually enable Secure Boot by default, you'd have to go really out of your way to enable it for a VM.

My very recent story with libvirt and secureboot resulted in blanket disabling of secureboot as part of the preparation for creation of VMs.

The reason: the VM refuses to boot when provided with an ISO (via virtual CDROM) with a meaningless error (permission denied: go figure out what permission and why was it denied and by whom).

Secureboot is meaningless / useless for most people running VMs, be it on own or rented hardware. It takes some pain and extra work to get it to work sometimes, and a huge amount of work to get it to work always. I doubt anyone was dedicated enough to get it to work always. So, I believe you are right. This is extremely unlikely to be a problem for anyone running Linux VMs, and the more VMs they need to run, the less likely it is a problem.
