Damned if you do, damned if you don’t.
First off, your information is incorrect. There aren’t 5 issues remaining of SUPERIOR FOES OF SPIDER-MAN.
But we hear time and time again from fans complaining that the books are taking too long to come out, and that we shouldn’t wait for the creators and so forth–that you want it now more than you want it by those guys. Not every reader, mind you, but plenty of them.
So in this instance the editor had a fill-in issue done. As has been proselytized for by the fans, at least some of them.
It’s hardly disrespectful to the readers. if anything, it’s an attempt to be the opposite.
The cover price is the cover price, it costs what it costs, especially at the numbers it’s circulating at. If you want those remaining 5 issues and beyond, that’s the trade-off. Again, not disrespectful, simply the cost of doing business.
