Speakers at large companies must get the entire content of their public presentations approved by PR and upper management well in advance. The process can take weeks even for completely innocuous information because accidental disclosure can have serious implications.
1. Disclosure of number of customers, number of transactions, number of anything can be reverse engineered by investors and competitors to derive forward looking information about the company's finances. Or worse, transactions related to specific customers so their financials could be reverse engineered. Good way to lose a client.
2. Disclosures of internal resources, urls, domains, architectures etc can be a treasure trove for competitors and malicious attackers.
Maybe it was a tongue in cheek joke because he was fully aware his content had been vetted 10 times over. Or maybe not and this is part of a pattern.
