So instead of a papal bull, how about a stack exchange with links explaining how (even if the church did not oppose the press itself) the church did attack its users for publishing information that the church was opposed to (i.e. claimed was false). https://history.stackexchange.com/questions/42677/why-did-th...
Or an article about how Luther was excommunicated for what he did with the printing press. https://www.history.com/news/renaissance-influence-reformati...
Perhaps the Church's complaints were more directed at the dissemination of information that the Church considered to be false... like the Wired article's complaints about AI's potential to spread false information. My point is that free speech is good. Free speech may include lies, but people are smart and even lies help listeners learn.
