Take heart: I checked this by taking a random screenshot, and browsing down to see how long it took me to find a commercial page. A quick sense of my trail was really encouraging:
- Open source wasm runtime
- Science transparency campaign
- Netherlands gov anti-climate change program
- open thesaurus
- GNOME conference
- France's portal of towns and cities
- Scientific measurement standardistion page
- Scientific journal
- free eBook library
- parked domain
- Linux community
- Open source graphics library
- placeholder/template blog
- A book publisher (selling books!)
It took quite a while to find a commercial site,and that itself (a bookseller) is a positive thing itself.
It seems like the screenshots are clustered in some way. That is especially visible when you zoom out.
