Some have tried to hide this, and there are links to such accounts. But, "Na’ama is direct. She’s not the kind of person to pretend about anything. In the third trimester, her condition is nearly impossible to hide anyway. And yet surprisingly, most investors have scrupulously avoided discussing the fact."
They may have avoided any mention for legal reasons.
Pregnancy is one of the protected classes. If they talk about it and then don't give you funding, there are potential repercussions, just as if they discussed religion, race, etc.
I read that, but I can't tell if you meant that she's direct about it but waits until/if the investors bring it up, or if she brings it up with every investor, like Ms. Miller's adviser suggested.
