@evan agree on both. People vote with their hearts, but what's happening is the techno-orcs have sucked the oxygen out of all the heroic old-time projects. Not an insider but I wouldn't be surprised if Wikipedia is dropping because it too is no longer needed as fig leaf. They took some risky bets (I know of abstract Wikipedia, wikibase) but they didn't flourish. Actually I can't think of any growing open project today that touches *mass* audiences. Signal with their 70 mln users comes closest.
