Spot on. There is no loyalty, it's a partnership.

You wouldn't pay 20% to Netflix to watch your shows, would you? But it doesn't mean you're a bad customer. And when Netflix raises the prices or includes ads, they won't say "oh, you've been paying us for 5 years, we won't do it to you".

If extra time is not compensated, don't do extra time. Even for startups: startups are ponzi schemes for the founders. Like for any job, you should consider what they offer now, not what they promise. Because startups generally don't meet those promises (that's the whole point of a startup).

But if the company respects you, you can respect it in return. It means meeting the expectations. If one party doesn't, the other party is free to end the contract.
