I think this is the only right answer. They try to provide the same interface which works for the most people.
Sorry, could have formulated it better. Hetzner did. I’m a happy customer of Linode. It seems they all have filters failing in different ways.
I tried them, but got basically the same treatment as OP with Linode. They just closed my account.

Cromite was suggested to me and it seems to work well: https://github.com/uazo/cromite
There’s also KID3 and Foobar2000.
