Can you comment on the loss of iCloud syncing? That is going to be the reason I leave if it's confirmed.
(full disclosure: I also know the developer personally and have watched as he evolved the product, and since it has comprehensive import/export features I know I can get my data in and out of it safely - and without being beholden to a subscription that adds effectively zero value)
It's a shame, really, I've been using 1Password forever and have kept at version 6 precisely because I want to limit my data exposure and have a bloat-free experience.
Goodbye, and thank you for all the fish.
