I did not get the feeling that the Bloomberg piece was about devs. Did I miss something? They specifically called out Apple Maps, which requires a lot of data cleaning.

In the US, maybe contractor/body shops are rarer around dev work? Mostly around the Department of Defense.

My point was that employers' ability to pull in lots of short term employees weakens their negotiating power. At least in Germany.

I think the point of the parent comment is that we're discussing software engineers, who certainly have a different negotiating power than the (presumably nonengineering) contractors mentioned in the article.
