I don't care. The vast majority of code written in the private space is garbage and not unique. Products are usually not won because of the code.

Would I send the source of a trading algo or chatgpt to a third party, probably not but those are the outliers. The code for your xyz SAAS does not matter.

I am probably an outlier in that I don't really care what corpus a LLM trains off of. Its its available in the public space, go for it.
