Is that one description or two? That is, does "static html" = "low quality"?

Two. Static sites can be of good quality as well as old sites. But in case the sites are of low quality and have less content in comparison.

These old sites never really received much traffic from Google over the years - How do you know?

Alexa ranks. Above 1 million. Other websites in the niche have Alexa around 2000. Not a tech niche. High search volume.

The results are bad for few keywords, and I'm not just saying that cos my site lost rankings. One of the website has two 336 ad units, above the fold, and a popup ad and inline text ads as well. Keyword repetition in inner links.
