I can see how working for Google, there is no issue using their cloud infrastructure... For other companies I don't see the benefit esp since Google is an enormous data broker to the US government and security infrastructure. Microsoft used a similar, yet relatively benign tactic, of copying works created in their dev environment and then pushing out the competition simply through free or cheaper prices.

It just can't be ignored that promising or lucrative businesses, workflows, models using SV infrastructure provided by Google et al, will just be passed off to those passing through the revolving door as "rewards", etc.
