>Many didn't know that Chrome engineers could run experiments on their tightly-controlled Chrome installations, let alone that Google engineers could just ship changes to everyone's browsers without any prior approval.

Ref. quote from article:
"Chrome engineers operate a system called Finch that lets them push updated Chrome settings to active installs, such as enabling or disabling experimental flags."
