Didn't the Dutch use the Malinois to bolster the breed in the last century as they were very similar physically and mentally to the herder, makes sense as it needed new blood.
Several years ago there were only a handful of breeders now like GSDs you can pick Malis up for less than £200 off donedeal so plenty of crap about which is a shame.
A lot of dutch shepherds have heavy doses of malinois blood, and definately a lot of shit bred malinois about now for small money, decent malinois + dutch fetch 750+ but the difference is the parents are proven and titled and prospective owners vetted
