If your source for "Dutch levels of weirdness" is just that article, then keep in mind that the VVD being "in power" meant that they were one of the parties in the government coalition. They have had to compromise with other parties through all of that time, and so it was not the case that those governments were only representative of a very small party of the electorate, as that article makes it sound.

(In my opinion, the Dutch system is one of the best implemented in practice, precisely because of its proportionality.)
