As for the above, well, let's just call it art. How should I interpret it? The analogy is that ants are affair partners, and so if I put some sugar water out, they'll all come out of the woodwork. Is this some kind of journalistic or legal exercise for building a body of evidence against Jensen? A mating strategy? I don't know! It could be both of these, either, or none! The limits of my own imagination are laid bare.
On the actual topic, though, anyone who doesn't see why this is a problem needs to think a bit harder. If the CEO puts on the show of being a family man, but is secretly getting hands-on with coworkers and spies, he's a liability to the company. It would be a stretch to say this would be acceptable behaviour even if he were above board about it, because it calls his overall judgement into question, but it would be marginally better. Remember, this is a guy who runs a multi-trillion dollar company that has limits on what it can sell to whom, because the product is a strategic asset. He can cause hundreds of billions of dollars of damage (and did!) just through his own personal behaviour. He doesn't get to have lapses like this, and if he does, is he making bad judgement calls elsewhere? It's not like it's hard to not sleep with your coworkers and clients. Billions of us do it every day.
Of course, this could just be the jealous ramblings of someone who doesn't have a sweet leather jacket...
You can leave sugar water in strategic places and then follow the ant trail to track where they are coming in.
Probably there will be an entire trail of ants in the morning - not just two. You can then track the place where they are coming in and block up the entrance point.
