Most big companies attract rule followers. They err on the side of avoiding taking risks like this, which is why they work there (and why there’s so many in this thread talking about rules). It benefits big companies to have mostly rule followers because you can’t have a too many people going in different directions. You need stability and a unified direction, that usually comes from the rulers making the rules. The fewer rule breakers generally find their way to the top, or get canned
This employee’s decision to break the rules, while addressing a real need in the market, must have really pissed off some people above, for better or worse. Google could have just rolled with it but I’m sure it would have stepped on someone else’s plans. Career defining moment, but they didn’t have the political capital it seems. I don’t think they will have much trouble finding work elsewhere though
