I've been a happy paying sub of Stratechery since October 2015, and would be glad to discover that subs have 'almost surely grown exponentially since [November 2014].' Just wondering what your basis for that assertion is? Looking at (admittedly poor) proxies like Twitter followers, Facebook fans, and estimate domain visits from various sources I don't see any sort of exponential growth...though to be fair the sources I am looking at go back to mid-2015. Again, poor proxies and would be happy to know Ben is doing this well.
