Long lived hifi equipment can be a huge offender, plenty of stuff still around from the decades between broad introduction of remote controls (before that, they were usually hard off) and broad introduction of switching PSU which aren't quite as bad as transformers (but early and/or cheap can certainly be bad as well) But I think "everyone" already knows that standby devices are a convenience that one should strive to avoid, the current fight is between people who insist on unplugging the USB charger vs those who refuse to do so. On this battleground, I think I see a strong case of perfect as enemy of the good: "refusers" are likely to react to pressure by ignoring the issue completely and might easily miss out on meaningful low hanging fruit.
