Google has removed two Chrome extensions after it was discovered that the software had code that served ads, which violated their terms of service. The two extensions were “Add to Feedly” and “Tweet This Page.” Each of these extensions had less than 100,000 users.
This past December, Google added a new policy that disallowed developers from using extensions to insert ads into more than one part of a website. Google requires extensions to have a single purposes and must be easy to understand.
Amit Agrawal, a popular blogger behind the website Labnol.org, sold the “Add to Feedly” extension and blogged about how he regretted doing that because the buyer inserted the ads into the plugin.
