Most butter here (and in a number of other countries) have measuring lines on the pack itself in 50g increments, so while I agree with you it's a nuisance to have an open one to deal with, the measurement part is usually a matter of using a knife along the marked line...
If the "certain brands" you refer to don't have those measuring lines, though, then a pox on them...
Pre-salted butter is another weird American thing that's completely unnecessary. Butter is also great for cooking and you can keep it for months in the fridge without issues.
It's not really an American thing. It's a pretty wild mix which regions use which how much all across the world (well, across places that commonly use butter obviously)
