While they are quite prominent the mentioned brands are not actual monopolies and you do see quite often locks, elevators and faucets from other manufacturers.

Abloy doesn't play by the language rules because it is originally short for AB Lukko OY ([LTD in swedish] Lock [LTD in finnish]).

I have never had any problems with Abloy locks. The previous lock on my current building started jamming when people pulled the heavy front door open with one hand by the key, but it was made by some german company. The current locks on the outside doors are electronic so you can not pull it with the key, but can open with one hand by pulling the handle after showing the key. Aparment locks are still mechanic. The new locks neither are from Abloy.
