You misunderstand my question.  Why was the choice of a blocksize of
1024 made?

I'm trying to understand how many devices, and why any other
manufacture would make, what seems to me, to be a completely insane
choice.

How long has Huawei been using a 1024 byte blocksize?  And why?  And
for how many devices?  Essentially, I'm trying to figure out if this
was a Huawei-specific mistake.
