Totally agree they should have provided a warning. Any Saas (and really would apply to social media, web mail, etc) should clearly warn before taking drastic action if possible. But I don’t see how you’d have dns without vendor lockin. It’s not like moving dns to godaddy would be better. Route53 is nice, but aws is also a vendor lots of people are locked to
Similar for ddos protection- you almost have to use somebody.
