Year-over-year, "revenue" and "profitability", or at least the not-for-profit version thereof, have been increasing for Wikipedia.

Every company in the world is trying to be in that exact situation.

Economics is not biology. Stasis is very hard to maintain. Typically, a business is either growing, or it is declining. Our current problems tend to revolve around companies that are too big to fail, not companies that are too big to succeed.

I would be much more concerned if Wikipedia's revenue and expenditures were flat over the past decade.
