Looking at the same page I come to a different conclusion. The pros it lists are permissionlessness, censorship resistance, and avoidance of a single point of failure. Cons are scalability and cost.

While they don't mention the word "trustless", those 3 pros are all things that you lose when you rely on a trusted third party. And since you pretty much always have to add a trusted third party to make the dApp useful, you effectively lose the pros and keep the cons.
