Even if you run your business from a server rack set up in your own house... who has control over your DNS? Dyn? How about your domain name?
I've had a website temporarily taken down due to an invalid complaint from Amazon, and it wasn't my hosting that was the problem, it was Dyn, who gave zero notice. The same company that's now owned by Oracle.
Seems pointless to worry about ceding control of your infrastructure hosting -- especially when you can craft it to be easily replicable on another service -- when there are plenty of other means to wipe out your online presence with little recourse.
