Zuck is correct because the barrier to a large user base is not skill but market share which requires substantial effort, luck, timing, and patience.

Nobody can put a dent into Coca Cola because of their market. Better products exist but there is really no way to compete against $5 billion in marketing allowing them to maintain $50 billion.

Cursor is ~1MM users a day. $60k/per user is high but considering this is a stock buy, Space X "made" $300BN in the first day that is ~20% or one day of positive movement.

For Musk (with his baggage) to create or steer that user base would require a significant investment and time. Why not just slap some coupons from an initial bump to acquire the user base, user experience, and IP?
