As an advocate for the free and open internet I wouldn’t consider them a force for good any more than Google, Facebook or Amazon.
They're not only a centralised point of failure, but also a man-in-the-middle for so many sites that they can effectively track people all over the internet through web and DNS requests, and fingerprint browsers through CAPTCHA scripts, and even read people's HTTPS traffic.
I consider them a hostile actor.
No organisation should have such pervasive access to people's lives.
