Noticed a suspicious element called give-freely-root-bcjindcccaagfpapjjmafapmmgkkhgoa in the chrome inspector today.

Turns out about a month ago, the popular open source [JSON Formatter chrome extension](https://chromewebstore.google.com/detail/json-formatter/bcji...) went closed source and started injecting adware into checkout pages. Also seems to be doing some geolocation tracking.

I didn't see this come up on hn, so I figured I'd sound the alarm for all the privacy-conscious folks here.

At this point, I feel like browser extension marketplaces are a failed experiment. I can just vibecode my own json pretty-printer extension and never deal with this problem again.

Well no, actually. Both halves of that statement are false.

Injecting ads will get you removed from the extension store if caught, while adblockers are advertised on the front page of the store.

Google's "Manifest 3" rules, vs. ad blocking, in Ars Technica.[1]

Did the JSON formatter with ads get kicked out of the extension store yet?
