For me, this is really about code generators in general. No need to center Adobe out here, as I can't think of a single IDE that doesn't generate all kinds of extra code that, to me, is useless 90% of the time.
You also should keep in mind that Muse is a beta and the Muse site itself was actually written with Muse.
In this case, I think Adobe deserves the benefit of the doubt. They're trying to showcase this product with hopes that people like us will come to the table and give constructive feedback rather than point to the past and say, "See, I told you! Damn Adobe!".
If you don't think this is constructive criticism, don't ever build a product in a space largely influenced by engineers. You need thick skin to be a PM and get feedback from engineers.
Adobe could be learning a ton about their product from this response. If they say to themselves, "Those Developers just want to say, 'See, I told you! damn Adobe!'", they will have wasted a major opportunity to better their product.
Their target market is obviously not developers, and there is a lot of feedback here i would just chuck as interesting but meaningless to the product. There is some, though, that will directly impact whether an engineer will laugh when his non-tech friend asks about Muse or shrugs and says "It's not perfect, but if your needs are light, it'll work" (just like I was telling my father-in-law Dreamweaver would work for the genealogy stories cd he wants to make for the family).
Adobe needs to get the product to the second place.
