I wouldn’t call it luck. Sure, the money is good, but their company is now essentially dead and should never be trusted to do anything good (just like every single thing Facebook does ends up having nefarious goals behind it).

Luck only in the sense of how early they were as a company and the premium Facebook put on them.

I still wouldn’t call it luck. Their company and product is now dead, and any good use they envisioned for the product is now forgotten in favour of nasty and user-hostile use-cases.
