Years ago I bought 1Password via a one off payment and set it up to sync via my iCloud Drive. It all worked great. Then they took VC investment and quickly every new feature was locked behind a subscription gate. I switched to Bitwarden. Then they took VC investment and I’m sure will end up down the same path (and you could never use a third party storage service with BW AFAIK). A password manager’s remote storage doesn’t need to be anything other than a safely encrypted SQLite file, you ought to be able to save it anywhere.
I think everyone should have a good password manager in 2024 and non tech inclined folks shouldn’t have to battle with upsells and spammy notifications as a price for being secure. If that means they’re using Apple’s offering, so be it.
