Sorry, I wasn't picking on you. It was just a good example.
I rarely if ever see anyone with head loops on a mask. Without them, it's amazingly hard to get a seal that would prevent fogging. If you have a seal that does prevent fogging, it's probably not very comfortable too, since it's pressing firmer into your face to create that seal.
There's a reason they keep saying "Wear the best mask you're comfortable wearing for the time you need to wear it". For most people, a super tight and uncomfortable mask is one they're likely to take off and not wear at the first chance. Wearing something that's more comfortable while not providing as good a protective value, provides significantly more value than nothing. Which is what happens when you're not wearing it because it's uncomfortable.
It's not a yes/no on protection, it's a spectrum of reduction. Getting the largest reduction someone can tolerate is very reasonable. It's not like we're all working on the COVID ward with very increased levels of virus floating around. Then again, the ventilation at some workplaces is so bad, some people may have the same risk.
