Here's the thing though: the marketers who are serious about paid media, and spending a significant portion of their budgets on it, tend to know that those algorithms exist and are smart/experienced enough to monitor and manage their campaigns accordingly. If you have good margins and/or a solid customer LTV, "boom to bust" isn't likely. If you don't have good margins and/or a solid customer LTV, the eventual demise of your business is the result of the economics of your business, not your marketing channels.
From what I can tell, a sizable number of the folks who have been running around treating Facebook Pages as owned media probably don't even know what "owned media" is.
