Meh. It's annoying sure but it's a small price to pay.
I've used the service for free since when it was the only service back in 2010. So I have no complaints if Evernote needs to shut it down. OneNote was in its infancy back then and an extremely inferior product - compared to today when it's simply an inferior product. It's comparable for what I need though and 0365 is prevalent in my industry anyway.
I've been only a basic user: 13.5 years of notes exports to mb not gb. To OP's point I'd be willing to pay $30-40/yr for the basic service that I use but that's likely not cost effective for Evernote. Fair enough.
Sure I could repurpose old notes and I have enough notebooks. That's not really in the spirit of things with a company that's been a good vendor for all of these years. It's been kind of a nostalgic trip, cleaning out the old notes. Some good: notes on kids sports, colleges, and bygone Christmas present ideas. Some not such as the notes on trying to find help for my heroin addict son; I can practically hear the desperation in my writing, or maybe that's just bad memories that are best deleted.
