Actually, the degree to which atheist materialists have embraced “multiverse” theory is quite amusing.
They profess to be empiricists and atheists have, at least traditionally, wielded Occam’s razor against the existence of an unobservable, transcendent deity. Now, in preference to one unobservable entity, they posit a vast, perhaps infinite, array of necessarily unobservable entities (if it can be observed, it’s in our universe, not another one), thereby ceding control of Occam’s razor to us theists.
The article states that most scientists have resisted the "multiverse" theory. I think we get a biased view of the beliefs of scientists because journalists select scientific opinion that supports their agenda.
