My theory is that it has something to do with the protection of the source. Ram, Mark, and George don’t want to have to sleep with one eye open. Being directly attributed to the source code responsible for the security of multi-billion dollar firms..... think about it. “We know” because “we were there” so to speak, and are literally trolling for info everyday. Who among us hasn’t written R&G attorneys trying to pry info out, or CJ, or MS. We’ve been scraping for info for years and years.
If they mentioned SFT by name, anyone could google their way into Mark’s backyard. Scary world we live in now.
