Please don't politicize these threads with opinions on competition, price-fixing and other highly volatile subjects. There's plenty of that type of conversation available out in the general forums. None of it is relevant to technical questions/conversations about Sigil anyway.

Sigil's generated cover is epub compliant. If people need special, vendor-specific, or non-compliant cover-image solutions, consider creating (or sponsoring) a third-party Sigil plugin to accomodate your needs. That's a big part of the reason Sigil's plugin framework was created in the first place.

Output plugins that take the stock epub version of a document and prepare it for specific vendors/retailers would be the perfect solution for those who only want to maintain one master version of their ebook, I would think. The Kindleizer, iBooksit, etc. ... That way, Sigil itself is left out of the equation. It's main concern is making a vanilla, compliant epub, afterall.
