I hate this one because it's true Einstein said we cannot measure the speed of light in one direction that is independent of the clocks' synchronization technique being used to measure.
And yet, somehow we changed that to "we don't know the speed of light in one direction!!!" Which is bogus - can you imagine if speed of light was different if you were pointing east vs west? In space, what is even a direction vs another?
Did you even read the wiki you linked? We've done one-way speeds, it's down below.
How do you synchronize the clocks and compute the measurement, without depending on the conclusion?
You run into a similar problem with Michelson-Morley: because the apparatus and the light both get distorted by any motion, you can’t even in principle detect the aether wind with interferometry. You need a non-comoving dynamic source, eg, LIGO with black hole collisions.
Their one-way experiments seem to require similar, ie, we can observe dynamics but cannot measure a static bias.
I'm over my head with your statement, but my guess is - Yes that's the point. Either you do 2 way or you accept 1 way clock-sync collusions.
My argument is it's not "We don't know speed of light in 1 direction". Also, there's another common youtube video that says "we've never measured teh speed of light!".
Those statements are just for click bait, shock value. It's not rooted in the science.

Criticism: It's not literally impossible.

Ah missed this - 2 days later, sorry.
