You mean- "remove your recording, cause it sounds to much like Lang-Lang", etc? I can't image such a complaint would really be sustainable at all. Unless they was an element of your interpretation which could convincingly be identified with someone's, rather than from the music itself. But that is would be a fairly absurd idea, since there are so many different performances and interpretations in existence, which typically derive from what is contained in the score itself.
Sometimes, 'warnings' are issued without any real substance, on the assumption that people will cave in because it comes from a large company.
If you are recording public domain piano compositions, have have the right to post your own recordings.
