Every business needs an exit no matter how disruptive it claims to be or how the founders of the business claims it is anti status quo or anti establishment.
The only entities and businesses that have that type of cash to acquire other "disruptive" businesses are "establishment" businesses.
Facebook acquired whatsapp for like $15B despite the business being unprofitable but they looked at the potential synergies of the deal. Whatsapp could be another ad revenue play (2 billion users on Whatsapp) when prior to the deal the app had no ads and prided itself on encrypted communications between users but it doesn't matter what the "disruptive" mission of Whatsapp founders were they are no longer the owners of the business.
NY times probably saw potential future synergies that more than justified $550 million price tag. The value of synergy was more than the premium that it paid for the athletic.
