You forgot to mention that a lot of editing work on wikipedia is done by bots (there is no clear way to decide how to pay for that). What is your opinion on Wikia and the deletionist culture that is rampant on wikipedia?
By the way, I don't know if you're aware that Wikipedia with its parallel corpus in hundreds of languages covering almost any subject is very important in NLP (natural language processing) and the development of AI with common sense. Wikipedia is also routinely used to build word embeddings for many languages. The Wikidata project is essentially a huge ontology - a database of entities and relations - very important for advanced NLP tasks.
So it's a valuable resource both for humans and AI. We'll benefit from Wikipedia indirectly by using AI trained on its database.
