Depends on the company. For example, you would never assume the employees of a 
password manager could access your stuff. That would be insane!

For a file sharing service - such as Dropbox - they don't need access to your 
stuff in order to share and sync it. Unless they're processing your information 
for you in a way that you find valuable, there's no need to give them access to 
your stuff in order to share it and sync it with other people of your choosing.

Which is why it's valuable to have it all encrypted before sending to/from the 
service, using passwords and keys that the service can't ever access.

For one, (see Third Party Doctrine) even if there are no bad actors in your 
services and they never get hacked, you waive your legal right to privacy by 
voluntarily exposing your information to any third party. That means it's 
completely legal for the government to search and seize everyone's information, 
without warrant or probable cause.

For two, it's not just the authentication that should be encrypted without 
exposure to the service provider. The data itself should be encrypted, unless 
the service provider is doing meaningful processing that you value and 
therefore choose to grant them access in order to do that processing.
