This is de-facto status quo in tech. Usually the carrot is that you can transfer into the company as a FTE in a year or two. I've also seen people go from FTE to a contractor doing basically the same job just with a different title. Honestly, there should be a mass class action by these contractors at Google. Maybe that will put an end to it all. Trump could curry a lot of favor by investigating these issues. It's as big an issue as H1B.
