I have two Chrome extensions in the store. They're not very popular and are really just features I wanted for my own use. I think I have less than 100 users total.

At least once a week I get emails from people

- offering money to add their "tracking" code

- wanting to purchased the extension outright

What they clearly want is access to my modest install base to push questionable code onto. I certainly am not going for these offers, but I could certainly see someone less financially secure giving in to it, and that scares me a little.

The idea of paid malware insertion in smaller packages is kind of troubling in general. How often just in life in general do we just trust opaque binaries to be clean.
