As a programmer I can understand that not each and every feature user space dreamed up to be exist in the actual software.
However as a past product manager, I cannot understand a software development company which lets one of the major competitors to get away with all user data.
On being a paid/free/cheap/expensive etc product:
I used to have a Premium Evernote account, that I let to expire after encountering a problem (which I do not even remember or care now)
I switched to One Note under a paid account, which was terribly easy BTW.
When One Note developed some reliability issues in MacOS, I switched to Keep under a paid Google account, which was difficult but justified due to One Note issues.
I did not switched back to Evernote, because of import problems of Evernote.
Currently I am looking for an isolated note taker for a hobby project, which might ot might not require data import from Keep but I like to keep my options open.
So kids, the moral of the story. If your software is not import capable it is difficult if not impossible to be chosen by "old" or "serious users with a long back story". And OTOH if your software is export capable, people would trust your software. I know I can gather all my data and leave Google, all services if I want to, in one or two days. So that I can trust my data to them...
