Seriously, would you want an entire multiverse of consciousnesses to all know they lived in a virtual reality? It would cause constant existential panic, increase the risk of internal attempts to hack or break things, destroy immersion, etc. It should be a selective privilege.
Furthermore, it should be associated specifically with those whose values align with truthseeking no matter what and whose profiles are compatible or can be non-coercively made compatible with higher levels of responsibility.
