1Password is terrific app, and I'm delighted to see its continued development. I use it alongside iCloud Keychain, and it's very valuable to me to have something cross platform for occasions when I need to use Windows and Chrombooks.
The whole subscription vs perpetual licence thing seems a bit played out at this point.
To me, all paid software is a subscription, in the sense of being time-limited. I own a copy of Microsoft Office 4 (still got the discs somewhere!) but since I no longer use Windows 3.1 the fact that I hold permanent license is not dreadfully useful.
Ultimately, if we want software to be continually maintained and updated - and I most certainly want that from a password manager - there is going to be an ongoing cost one way or another. I prefer subscriptions because it makes that explicit - this much money for this much time - and I can make a purchasing decision accordingly.
