isn't that just your guess though? Zealous over-optimization only gets you so far: illegally extending a monopoly requires active malice and disdain. Really removing users' choice. Forcing them to use your products.

For example one of the things I would do as an evil product manager at Google is introduce active detection of Firefox - even if the user agent string has been set to Chrome to get me to serve unbroken pages. I would have engineers actively fingerprint Firefox, and if I figure out the user is using Firefox, serve them broken pages. (Even if it works perfectly well in Firefox if they pass my detection, and even if they identify as Chrome.)

Would this attitude be a good fit for a product manager for Google? I'm really evil.
