Kind of funny, I bought a 5 gallon of ink that was sitting around my local screen supplier with "bad ink" written on top. I made an offer , picked it up for the cost of a quart and it's been printing just fine... shrugged it off as the user must have been doing something wrong. Score!

Imagine that... Happens with equipment also...

You never hear the black ink was bad. The black ink cracked. The black washed out. Why do we have so many whites on the market. Can't each company just make one white and not have 4 or 5 of them.

Substrate

Pigment load

Weave

Shear

Viscosity

The short list above could constitute five inks... and that is only a short list, super-glue (cyanoacrylate) is not the only adhesive for many similar reasons.

There is never one single perfect universal answer...

If there were only one ink - why bother to have more than one ink company?

And yes there can be other colors outside of white that have problems, including black, but the pigment load of white ink by itself is a contributing factor.
