Or is it extra safety to use the CLI?
Arguably it is easier to verify that a webapp is not sending the data to a 3rd party, than it is to verify that the CLI tool doesn't (easy network inspection from the developer tools).

However sure, having the piece of mind that this will not happen may still make it more worth it do it yourself.
