Again, the Bessemer process for making steel: Bessemer found a way to make large amounts of good steel cheaply.
He tried to sell his way to other steel makers, selling his method and his advice.
They tried to follow the Bessemer process, and they failed. Their steel was crap. They were pissed, and blamed Bessemer.
In the end, the only way that worked was for Bessemer to grow his business and train steel making engineers under his command and authority.
