Mackenzie is almost 100% BrainDrop. Those similar writing styles almost proves it.
But besides that, realistically, why would any developer give their Patreon info (since Mackenzie posts there) to a random person on the internet? Developers who have functional teams only have 1 person with the Patreon account info. Let alone a non-paid PR person.
I've also thought she is actually a real person, but one of BD's IRL friends or even wife. Either way, it's not good.
Between the Mackenzie account (assuming she is BD or his IRL friends/wife) + guilt tripping people + continually delaying + not pausing payments. Braindrop has become the worst of the bad reputation developers. Most of the others either vanish (ISCTOR) or at least don't dig their hole deeper by making promises and trying to get people to not un-subscribe via playing on peoples sympathies.
Would've been unthinkable a few years ago, during the peak of the Bailey Cult and such.
