Twitter has a market cap of $13 billion mostly because of content produced by its users. The only possible way it can make money is by showing ads to users (getting them to do free labor).
Twitter is made up of it's shareholders and workers. The workers have been receiving a salary(profit essentially). Twitter shareholders make money when the market cap goes up(profit essentially). It's likely a semantics discussion about what "profit" specifically means to each person more than anything.
Fortunately, profit isn't defined so subjectively when talking about a corporation.
