I know that I’m cynical, but just the fact that she got him to send revealing/ dangerous texts is suspicious to me. While many men are happy to send unsolicited, I’m betting that it takes some encouraging to get someone like him to risk it due to the potential of looking like a creep and potentially hurting the value of your baby/ company. She must have really built some serious trust somehow.
The obvious way to dig gold would have been to break up his marriage and marry him. The 2nd most obvious way would be to get damaging information and sell it.
If the gov wanted to embarrass him, it would have been much easier to do it this way (the Russian honeypot way) than through technology overreach. Because the honeypot method creates the embarrassing info and harvests it. The tech way depends on the embarrassing info being there in the first place.
