google used to own 7% of uber. I don't know what it is now, but lets say its 5% that stake would be 3.5bil at 72bil valuation . If they are getting .34% essentially they are losing money from GV losing money as a share holder while waymo is gaining some, but they are both google companies.
I don't see how this lawsuit benefits google shareholders as a whole. They just wasted money on lawyers.
