I am using several VMs in Qubes. All of them are Whonix and I use Tor browser.
I want to be anonymous on some of them (mainly to authorities).
Could it threaten my OPSEC if I identify myself on some of the VMs, if the other ones should be anonymous?
I think Tor browser mitigates fingerprints, but maybe it is viewable that there are similarities regarding the identical hardware or something. Not exactly sure how well Tor browser does the job.
I am never using more than one VM at the same time.
