Fundamentally, maintaining MDN is costly because of the rate of instability in rapidly changing browser APIs. Those APIs change quickly and inconsistently because they’re managed by a centralized cabal of a few corporations with a combined multiple trillions of dollars in market cap. And yet, somehow it’s Mozilla, the browser vendor with the least money, that ends up saddling the cost for MDN. Why is this? In general…

These companies really are the pits. [0] Of course, my other bugbear here is that this constant churn adds non-trivial quantities of no…
