(This is just my opinion)

For many who have updated with the japanese 2.00 update and own an us psp the settings may be a little different. The overall procedure of an update is to flash the bios right? so if you had a us PSP and updated with the japanese update some parts of the os(operating system) may have not been flashed and may still have the same files as the previos os did. So my theory is that when we used the japanese update on our us PSP's (v1.5, v1.51 or v1.52) some of the previous files have not been updated because they are region protected.

Get what im saying?? Ok if not dont worry ill explain it in a different way.

Ok when u took the update for the japanese PSP it has a different region code on it so if you put that on the japanese PSP it would update all the files even the ones that are region protected because they have the same region. Now if you take the japanese update and placed it on a us PSP some of the region protected files WILL NOT update because they dont have the same region code. So what you are left with is a partly flashed bios so it is like you have a hybrid now part US and part JAPANESE?

Now do you get what im saying??

So what i was thinking is that sony came out with those complaints the the japanese update will ruin you US PSP because it has a partly flashed bios and some of those files are from your previous firmware and there will be security holes which you CAN CRACK

WOW! i took me a long time to write this but maybe this will spark up some ideas

Maybe for 2.0 you are right, since we can't compare yet with the US PBP; but for 1.50, 1.51 & 1.52, the Jap and US PBPs have the same md5 so are exactly identical.
