"Thanks to G/O's stubborn insistence that it only wanted Quartz's assets and not the corporate entity"...
this is not stubborn it's quite common and is absolutely the right thing to do for many companies interested in another business. If they buy your entity (stock transaction) it comes with all the legal liability.
Zach probably doesn't understand how much more likely his deal was to close as an asset purchase rather than a stock purchase. A stock purchase comes with lots more diligence and legalese. If they are buying your stock they are buying all your baggage and potential legal matters, it requires a lot more work including a laundry list of representations by the seller. G/O did everyone a favor by sticking to an asset purchase and getting the deal done. that's where the positives end it seems.
