I work at a venture-backed company, started by people who already have enough money of their own. VCs don't make up enough share of the board to force them to do anything. Given that the founders already have money, what is their incentive to exit? And if I don't like it as an employee, sure, I could take a job somewhere else. Somewhere else that also likely has its own reasons for taking as long as possible to go public. What if the way it used to be was the anomaly, and now is normal?
