Cut scene to me explaining my new product to a Google VP (hoping to get funding) who instead made a crappy copy and released it 6 months later. Don't meet your heroes.
From this example the same feeling would be generated by someone else internally already working on the same idea without needing any prompting from anyone in the actual meeting. This can actually be quite common in games where people will give a lot of unsolicited design ideas as feedback or part of bug reports. There's going to be collisions there without anyone's ideas being copied or stolen without credit.
