I think the implication wasn't that DD was pouring fuel on to the fire of "restaurants closing", but rather that when they, a company that works with restaurants (many of which are closing) are doing so well that they can IPO to the tune of $60B and make their founders/investors VERY rich, this can pour fuel onto the fire of "tech companies making money at the expense of others".

I feel that regardless of your feelings on the truth of that last quote, the connection can still (and will) be made by many people.
