But Wikipedia is no where near the same service it was in 2012. Dozens (if not hundreds) of features, increased traffic demands and higher availability, it seems obvious that the platform would have to grow.
So while yes your argument is true that in fact the platform is growing, that however as an argument hete isn't really demonstrontative of a correct understanding of the problem the author argues.
How many employees is the right number? Is "1" the right number, is "300" the right number? How does Wikipedia's growth compare to other well-known companies?
