I dont think its really a problem. I never seen a game that denies the ability to see light in the dark as well as stars and moon in the night sky for real. 😉
I could see the argument that opaque fog blocks vision through it because it is opaque. Natural darkness does not block vision through it. And the magical darkness created by the Darkness (which says "nonmagical light can't illuminate it") is also opaque and therefore also blocks vision through it.

Per the same link, the separate question of "how do they work, then?" is "blocks vision entirely", i.e. they work like fog/foliage do in the real world, not like darkness does in the real world.
Tangential warning: the rules for dim light, patchy fog, and moderate foliage do the same thing of folding all three together, but their shared behavior matches none of the three in the real world.

I think it is reasonable to say that the rule explains what "blocks vision entirely" means in terms of game terms. None of them otherwise block vision through their space. It is other properties of opaque fog and magical darkness that cause the blocked vision through their space. This would all be consistent with RAW.
edit: changed a there to their, out of embarrassment.

Darkness, opaque fog, and dense foliage all behave the same way, as all of them follow the rules for "heavily obscured". While it is common to house-rule otherwise (lord knows I do at my table), RAW is that opaque fog and darkness must work the same way: you can see through both or neither.
