I very much doubt it was a PM in charge of reading the TOS for the enterprise certificate program. When you need to sign a contract on behalf of your (multinational, FAANG) company, you get your legal team to go over it.
The legal team would have reviewed the TOS but they probably weren’t looped in when some PM got the idea to use the certificate for this purpose.
In my own experience people often avoid consulting legal when they think they can get away with it (or don’t realize they need to), although I’m sure it varies a LOT based on company culture.
