Big corp. starts illegally stealing data through improper means and not following T&C of small-funded startup
and there would be an uproar.
All those fluff tech-sites that treat Apples new Iphone with incremental changes as "big news" would suddenly have months of juicy news to bash the big corp to the point where their bigger media-parent companies would follow suit and damage the big corp indefinitely.
Maybe folks should just call "a spade a spade" here.
The startup violated the T&C of ADP and whether or not ADP is 100% honest of the server-volume from this company, the startup still committed an illegal action.
You can "disrupt" industries all you like, but when you break explicit contracts, you can't go crying on social media about it and expect things to work out for you.
As far as PR goes, ADP won with this line:
"We’re willing to work with our clients who use Zenefits, and with Zenefits directly, to find a solution that fulfills our clients’ needs and protects their data."
