I don't think the FCC cares about interference unless it affects other people.

Look at TVs and computer monitors for example. I've got a Samsung SyncMaster T240 monitor that blasts out annoying noise all across the 2m ham band (and nearby police and fire bands). I've got to turn it off if I want to usefully scan those bands with a radio that is within a meter of the monitor.

Yet it passed FCC certification. Yes, it is noisy, but even if I were in a small apartment it would not be noisy enough to interfere with someone in another apartment. It just is a problem near the monitor.

Not all TVs and monitors are noisy. When playing with an RTL-SDR on my 2017 iMac I've never found any significant noise coming from the iMac for example.

Unfortunately this is something that reviewers don't seem to ever test.
