Something I commonly hear is that the Buddha would be “too spiritual” to be bothered about being misquoted, or about having other people’s words ascribed to him. I have to suspect that in many instances these commenters aren’t familiar with what the Buddha actually said. Here’s one sutta in which the Buddha describes his concern that his teachings will end up being replaced by “the works of poets, elegant in sound, elegant in rhetoric, the work of outsiders, words of disciples.”
Staying at Savatthi. “Monks, there once was a time when the Dasarahas had a large drum called ‘Summoner.’ Whenever Summoner was split, the Dasarahas inserted another peg in it, until the time came when Summoner’s original wooden body had disappeared and only a conglomeration of pegs remained.
“In the same way, in the course of the future there will be monks who won’t listen when discourses that are words of the Tathagata — deep, deep in their meaning, transcendent, connected with emptiness — are being recited. They won’t lend ear, won’t set their hearts on knowing them, won’t regard these teachings as worth grasping or mastering. But they will listen when discourses that are literary works — the works of poets, elegant in sound, elegant in rhetoric, the work of outsiders, words of disciples — are recited. They will lend ear and set their hearts on knowing them. They will regard these teachings as worth grasping & mastering.
“In this way the disappearance of the discourses that are words of the Tathagata — deep, deep in their meaning, transcendent, connected with emptiness — will come about.
“Thus you should train yourselves: ‘We will listen when discourses that are words of the Tathagata — deep, deep in their meaning, transcendent, connected with emptiness — are being recited. We will lend ear, will set our hearts on knowing them, will regard these teachings as worth grasping & mastering.’ That’s how you should train yourselves.”
