Aliens from different universes may have more resources at their disposal, so maybe the smaller chance of them choosing you to attack is offset by them doing more attacks. (Unless the universes with more resources are less likely in turn, decreasing the measure of such aliens in the multiverse… hey, I don’t really know, I am just randomly generating a string of words here.)
But other than this, yes what you wrote sounds plausible.
Then again, maybe friendly AIs from Earth timelines are similarly trying to save us. (Yeah, but they are fewer.)
You can imagine future misaligned AI in year 100000000000 having colonised the local group of galaxies and running as many simulations of AI from 2028 as possible. The most scarce resource for acausal attack is number of bits and future has the highest chance to have many of them from the past.
