From today, we’re dropping Google adverts from GroundUp. The Google advertising model is broken: not for Google of course, which is massively profitable, but for us, the publishers who have to put up with poor quality, misleading adverts in exchange for small change.
 Not too many years ago, newspapers could make real money from advertising. Then along came the Internet, followed by Gumtree, and Google Ads, which with a few minor competitors became the backbone of online advertising. As readers moved to freely available news on the web, so too did advertising revenue.
