Monero devs knew that an imminent update was necessary to protect their investors from the asic influence. Aro devs were aware that one acct was controlling over 50% of the hashrate in a supposedly decentralized mainframe and did nothing for a really long time. even when it was apparent that the individual responsible was destroying the coin's value.

 Again if they had an actual financial investment in the project, they wouldn't have let the coin fall from a stable 1k sat to lower 200 sat before updating the limitation to the algo.

  By also waiting they gave this guy a chance to accumulate so much coin that not only did he bank from severely dumping the coin but also has the ability to manipulate the price for a really long time. In any other sector, this guys will be investigated for collusion.
