For those using 1Password, this isn't as bad as the headline implies.

1. This doesn't apply to local data

2. This applies to metadata, rather than passwords

3. This only applies to an old vault format changed in 2012 used for syncing via external servers [edit, specifically dropbox or folder sync, still in use for that it seems]

So 1Password leaks your metadata if you use the old vault format from 2012 and upload your passwords to a public service (or share them some other way), but that's perhaps not such an upworthy headline.

Personally I would use local wifi sync and keep your data local, whatever password manager you're using.
