This is the same model of buying things on amazon too -- once you've bought once, it's easier to buy again. Why spend time going to another shop when you can just use amazon to buy multiple things. This ease of use philospohy goes way back to the one-click patent. If I want DNS, why wouldn't I go to amazon, which has all my finance details, and a decent interface (and even API), rather than choosing another DNS provider, setting up my credit card, and having to maintain an account with them. So I choose DNS via AWS. Then I want a VPS, but why go to linode and have the overhead of another account when I could do lightsail instead?
