Employees pushing for change from the inside is probably the only thing that could ever make Google change, so this is absolutely a good thing.
If you are an engineer at Google and can't get a job somewhere else, I don't know what to tell you.
Something few people seem to understand about massive companies is that they employ some of the most niche specialists imaginable because they're literally the only business that needs those skills. Working you way up and getting more and more specialized can be very lucrative, but also very limiting in the number of employers who want your skillset. Leaving usually comes with a big step down in terms of money and title. You're essentially dropping back down to where you were before you specialized. It's not hard to imagine a lot of senior engineers at Google might feel a bit trapped there.
