- for low rent income (this is generally the real problem), there is subsidised housing and rent control. There are many social housing projects, but generally it's not enough, so you might be on a long waiting list if you are trying to leave mom and dad, or if you live in a student town, etc.
- for people with higher income, there is still some protection for renters, but less control. Still, there is also a huge demand for these houses/apartments.
So the rent control absolutely helps in a difficult situation, but it's also definitely not a cure-all. Rent in Amsterdam is actually in the top-5 of the world (with HK and New York); but if you are prepared to travel a bit more, you can get affordable housing.
So this is why these links/articles are not necessarily contradictory. Yes, there is rent control and it helps to some extent. Yes, there is a housing shortage. Yes, it's a case of Eurocommiesocialism. On the other hand, there are no living coffins, and I think we can all agree that at least is a good thing.
