For example, I inherited a domain 12 years ago using it. At one point I tried to move to my personal host, but my personal host has bad DNS features and I couldn’t get my site configured. I was able to move it back (panicked I just went back to the service that I knew worked). And then I was stuck in a six month period where I couldn’t transfer it again. And then life happened and it’s three years later.
That might not fit into your logical conceptions of how people make choices. But I think it’s very very safe to assume that many customers are upstanding people.
