-Forever- is never true unless your offering is open source. 9/10 startups die and I will not pay for a service unless I have an path to migrate to my own server if the service goes under.

Leaving a blog engine should be no different than changing an email provider. Point DNS somewhere else and optionally backup/restore via IMAP to the new service.
