Doesn't matter too much what Google/Alphabet shareholders think. The controlling majority is with the founders, and the company is not going to the markets anytime soon to ask for more capital.
The only result of a lower stock price that I can see is that Google employees might demand cash instead of stock for compensation. (But Google still does make enough in cash.)
And by 'demand' I mean: get unhappy, be more likely to leave, and for new hires, be more likely to take up alternative offers instead.
