The 1Password situation is complicated because the people who run the company make it so. There's always been a push to get more income with less effort, not that that's wrong. But what frustrated me, and finally moved me off of 1Password, are the instances where the founders and staff responded in an obstinate way that "this is just how we're going to do it, and we've decided not to hear anyone, however loud you may be." Then after sometime when the noise seems high enough to cause damage, they backtrack (like it happened with the MAS-only decision). The only word I can use to describe AgileBits is "disingenuous". It sounds harsh, but it has a history of being so.
AgileBits has also used dark patterns, if I may call them so, on the website to hide or obscure what's available but not considered favorable by the company, and prominently push what's considered favorable by the company as if that were the only option available (one visit to the home page in the last couple of years is adequate to get this). This ought to be shameful for any software company, especially one that claims to care about the users.
When it was originally created and stabilized, 1Password was a great solution, almost like Dropbox in simplicity and value. But the focus has been sorely lacking on other platforms, like Windows (and of course, nothing on Linux). There doesn't seem to be a lot nowadays to justify what the end user gets from the subscription when there are other options out there (that didn't exist several years ago).
Ever since I started using Linux, I've looked for solutions and have been trying Enpass once in a while. [1] It's free on all desktop platforms and has browser integration.
Edit: Of course, it's also been quite sometime since I started using Keychain Access and Safari on OS X/macOS/iOS.
