Today, I’ve never even heard of anyone say that something shouldn’t be published due to T”SbP being Baal Peh.
When was the last controversy over whether something should be written down/printed? Is it discussed by Rishonim/Achronim or was it already regular to write down anything already at that stage? Was it normalized even earlier?
EDIT: I’ve spent over 20 years learning Gemora. Yes, I’m aware of Rabbi Yehuda Hanasi, Ravina and Rav Ashi, etc. I’m asking when we evolved to where we are NOW, where it’s not even a consideration. Not when we started writing things down.
