There are a lot of countries in EU which have, IMO, better work culture and fairness of negotiation as the guiding philosophies behind the work.
If Google did this in the USA, it wouldn't be seen as much. However, they have strong laws against this in EU, and this incident would not portray Google in favorable light, IMO.
I also feel that it is high time engineers realized that fairness in work is something we'd all love to have, and historically, skilled people have kept unions to ensure that they don't get screwed over.
I believe that at the end of the day, if you need fairness in negotiation, you need to have a way to express it, especially if it isn't supply driven.
