what is this cloner apologia? houdini 6 (and 5, maybe 4 too? I might be misremembering that last one) are not "houdini", they're SF with its nature obscured.

Houdini is always houdini even if the code is based on stockfish.
There are stockfish's with some changes when the author does not hide it or hide the code but the author used a different name for it.

The Huntsman is a specialized, open-source chess engine developed by Jörg Oster that is specifically designed to calculate and find forced checkmate sequences faster than standard engines.

It is a fork of the powerful Stockfish engine but people do not call it stockfish.

You can claim that if the author does not release the source code we should not use houdini but I see no point of complaining about the name houdini.
