Well, The Odd Gentlemen developed the game, but the latest incarnation of “Sierra” (http://www.sierra.com/) – Activision’s so-called indie label – is the distributor / publisher, so they’d be the ones responsible for how the game is sold, bundled, etc.
It was certainly not handled in the best way, but there was a recent post on the Sierra Facebook page that indicated they may be looking into this, so let’s hope they straighten this out.
This website – SierraGamers.com – is dedicated to the old Sierra games and was created by Sierra’s original founder, Ken Williams. It’s not really active any longer.
The best place to make your feedback heard is to post and/or send a message through the official Facebook page of Activision’s Sierra label: https://www.facebook.com/OfficialSierraGames/
