While I appreciate the approach of making "the world" a bit better once you see a chance to do so, I also don't think a company like Google should (be able to) leave it to random internet users to clean up their mess.

They could offer a bounty.

They could also hire people to do that necessary job.

I assumed they did.

Yeah, don’t assume that.

I tried the report abuse button and got a 404 when submitting the form. Lol, classic Google.

EDIT: My guess is they delisted the extension right about as I was submitting, since the extension page loaded, but the report submission failed, and now the extension is also gone. Maybe a cache purge was in there somewhere.

I reported abuse few minutes back. Google pulled it out shortly after that.

Also I am pretty sure Google has a "karma" number for users (just like reddit) in the backend where they automatically take down if report is from a user with high karma.

It's Google, so, no?

Google’s automated systems do have anomaly detection that would flag it if there were many reports though.

That's exactly it, dogpiling can be discarded as anti-competitive behaviour.

It works on other, bigger and more important Google properties what makes you think the Chrome store handles it properly?

aaaand its gone. Worked two minutes ago, now the link responds with 404.
