We were in the same situation. But we were completely open with our YC founders and they helped us a lot in getting into YC and with tons of advice. It seems like you are building the relation ship wrong based on some sort of deception. I would think about it.
Without knowing much, this does come across as very hypocritical of them to do this to you. It seems like the type of attitude that would be frowned upon by the YC community.
This works OK when you have direct relationships with the YC Founders -- but when you are only tangentially connected in a big company... It is hard to know where rumors go.
