The entire thing is a tongue-in-cheek take on "we won't change the price of our pizza for a year" but they make it sound like a mortgage. You can even go online and get pre-approval for your pizza.[1]
To me, this smells of some marketing people thinking they're really really clever. It's fairly well-executed. But just completely tone deaf. Some people are losing their homes. They're trying to feed their children[2]. This is not the time to goof about the absolute fucking dystopic idea of food mortgages.

[2] My wife volunteers at our kids public school's snack program (Canadian schools generally don't provide lunches). The school has a very wide range of income levels, so you get everything from kids who ignore the snacks (fruit, veggies, sometimes cereal bars), to kids who are sent to school with an empty container to bring food home. Luckily there are some really good social systems in place to try to remove this responsibility from a child, but it's soul crushing to see. This footnote is tangential but I'm having a very raw moment of anger, sadness, and hope.
