Can you elaborate how? I ask selfishly, but it would be interesting to know.

I have a hunch that one of the main reasons I wasn't sent one was because I said I use Firefox instead of Chrome -- I thought that lying would be a bad idea, even if they never found out.

I had that hunch too (of course, pure speculation). Coincidently, I've now moved to Chrome primarily anyways.
