There is no reason to assume that the same physical rules and limitations of our own universe apply to the universe that is simulating us. Our universe could be a drastic simplification of the "real" one, indeed this simplification is the kind of potential evidence the article mentions us looking for.

I remember reading once that the limitation on speed of light could be a performance optimisation. Isolating each "light cone" of local spacetime allows the simulation to be distributed and run on separate compute clusters, because it limits things to local interactions rather than universal ones.

Things in superpositions only becoming "set" after observation... that is just lazy evaluation. It's fun to think about.
