I really tried to read the comments on heise.de … but their website is the perfect example if ad revenue drives a company instead of providing value to their readers. Why do users have to create another page impression to read a comment?

To Heise's (slight) defense, their forum system is at least 24 years old, extrapolated from checking the date of my first comment on it. Probably even older. Apart from driving page impressions, there didn't seem to be an incentive to make the experience smoother, as user engagement is still very high.

You dodged a bullet there. Heise is infamous for incendiary, low quality discussion.

heise is older than online ads.
