I am using "access" in the same way you might access funds from your bank, which I hope includes the usecase of "I want to withdraw all my money" rather than "I can only take out the last $1000 I put in". I would actually be much more lenient iMessage organized messages better, as many other chat apps do, but it doesn't–I can't search by date, I can't sort attachments by filesize or even given an attachment jump to where it was sent (a big problem if you get sent videos!), if you scroll too far the app scrolls to a crawl, to say nothing of how little you must value your time to want to do that. I am merely frustrated that an app that provides no way of doing fairly common things also blocks people from doing this in any other way, and in doing so effectively does prevent people from accessing their data.
