that is the true, the fork novel it is their fault not miners' greed.
Are you sure that what you are saying . Because you want blaim the developer team for the down in the price of the Bitcoin price which totally regardless point in my opinion .
The increase in the price depends only few things .
first thing is the increase in the transaction speedily and second reason of the demand by the users .
If people will buy any coin speedily then this is usual that the price will increase but if everyone will sell then absolutely price will go down , then how you can drop the team.of the coin in the fluctuations of the price .
Here development team only help the users and make the coin better with new new upgrade programs and miners job is only to mine the Bitcoin and to tell the algorithm of the coin that the transfer of the coin from one address to another is right or not , and for that work they will get money in form of btc reward .
