While the statement about what has driven the recent boom is wrong... I think it should more accurately be replaced with "Many major lables attempts to cash in on the vinyl boom reflects...".
As for your reaction to Scorpio and Nirviana, I think you may have missed their point. On Scorpio, they are bemoaning the quality of Scorpio and sorry that people buy them since they are reasonable priced and readily available:
Scorpio finds itself in an enviable position for capitalising on the post-IKEA generation’s interest in buying something physical – no matter its quality – at a cost nearly equal to that of a full album download.
And about Nirvana, they are just calling for more normal non-Scorpio vinyl:
Anyone should be able to walk into any record store in the world and buy a standard vinyl copy of Nevermind for a reasonable price, rather than confronting the 180 gram pressing or the deluxe quadruple LP that fishes for their cash from a lofty wall display.
... although I do believe the Nirvana catalog is soon to come out as single titles in non-180g non-colored vinyl.
In conclusion, I see the thesis of the article as a call for more regular weight, quality single-title vinyl at a reasonable price, instead of the 10+ LP mega-sets, heavy-weight vinyl, and novetly records (Jack White's Third Man Records comes to mind) which can make records seems like a circus event, which I can't say I disagree with.
But you can also read into this a critique of the buyers of music. If someone isn't interested in a flexi-disc sent off in a balloon by Jack White then it woudln't go for over $1000 (it takes two to tango), and if some people cared about the music more than being hip (and there is definitely this segment in any pop fad which vinyl is to a degree at the moment in pop culture) then they wouldn't buy the Scorpio music and the Crosley turntables from Restoration Hardware.
