From my point of view this was not hostile at all: I used 1Password with Dropbox sync for years and absolutely loved it as a personal password manager _for myself_. But sharing of passwords with family was a real pain. I gleefully signed up for cloud-hosted 1Password Families at launch and haven't had a bit of regret. Of all the subscription services I use, at $4/mo 1Password is easily the best bang for the buck.
For sharing, it's just sooo much easer than trying to use Dropbox:
I can invite family members just by entering their email address and 1Password walks them through the setup.
I can create new vaults with the click of a button and easily select who I want to share them with.
I can revoke access to members just as easily
I don't have to have a Dropbox account and I don't have to wonder about whether I've set the right permissions on my vault files or whether my free Dropbox quota has been reached.
I don't have to share _my_ vault keys and passwords with someone else to give them access to a vault.
I can still export and back up an encrypted vault whenever and however I want.
It's no accident that all of these features are the same ones that make their product so attractive to businesses as well: ease of access and sharing are both essential for adoption by businesses.
One more note: I still have my old standalone licenses and can still go back to 1Password 4/6 with Dropbox sync any time I want and not pay another dime, as 1Password still has links to download the older versions on their website: https://1password.com/downloads/mac/
