Oracle was also a high level sponsor while advertising the crap out of it's NAS and VM products all over Las Vegas, and the Oracle EMC relationship is very frosty. Just because a company pays to be part of the vendor show doesn't make it "Weird".
Of course EMC will sell you tape, they are a company that "sells" things and customers get what they want. Tape is not dead, never has been close, and "Tape Sucks" was the marketing of Data Domain prior to the purchase and EMC rode that for a bit to grab the market share the much smaller Data Domain couldn't get.
I'm not sure what your intent with the article was. Last minute dash to a deadline? Try to get your Stornext stock up? Very little to do with EMC actually, more of a simple comment on tape, but I guess trying to paint EMC as "wrong" gets you enough page hits not to have a failure of a opinion piece. If you get more desperate to get page hits maybe you can change the title to EMC no longer thinks tape sucks, but cups the balls since you've been on this weird 12 year old sex reference kick lately.
