Are you saying you expect to pay one time and never again and want continued support for the lifetime of the app?

Not GP, but I do want to know that I have a path to having ongoing access to my data (which could include a fair and usable export process into a format that’s at least readable [PDF, docx, tex, other]) without a permanent on-going expense.

I see this reponse a lot after I comment on a product which doesn't make it crystal clear on what they mean by "one time purchase". It's a great draw but most of the time it's disingenuously false in an environment (software) where it's almost impossible to offer that.

I have zero issue with developers charging for a version 2, updates, maintenence, etc. Just make it crystal clear.
