A brouhaha over adware-laced Chrome extensions has forced Google to remove two from its store and possibly exposed a wider issue. According to the original developer of Add to Feedly, the problems happened after he sold his plug-in — created in a few hours — to a party for a too-good-to-be-true four-figure sum. As detailed in a blog, he discovered that new code was injecting ads into every page browsed without approval, angering users and lowering its rating.
