on the substance, you should have no problem with R Yehudah: if he was so strict with a regular baal aveira, kal v’homer with worse cases.
Conclusion of keeping it quiet sounds problematic, maybe that is what you are pointing out. When I questioned that going back to R Yehudah, Rav suggested that maybe at R Yehudah’s time, people would understand this properly, but at later times, they would start thinking worse about Talmidei Chachamim in general. But, I think, the main thing we can take from the gemorah is that this is a trade-off: on one hand, we want to punish openly to show that we stand to the aveira and T’C; on the other – we don’t want people blame all T’Ch when they hear about such cases. If someone ealrned this sugya further, please share.
Note specifically comparison of Rebbes to Malachim – and rejection of “we need him to teach” in favor of “we do not need teachers like that”. This does not seem to be rejected at the end, only the public cherem. Would it be a leap to apply this notion to books of Torah that are same as teaching Torah? does not have to apply to science books, or fiction, or even Jewish songs.
