This fatalist attitude is just as bad as the overly naive attitude that I'm sure left many employees of this company feeling screwed.
Employees have agency. Founders don't have some magical power over you with which to screw you. You choose to work for them in exchange for money, stock, whatever. If stock is a sizable part of your compensation, you probably should be asking a lot of questions about it. How many shares will I get?
How many shares do you have? How is the company doing? What are the future plans? When am I going to get liquidity? Do your own accounting. If they won't give you the information you require, don't join! If the company isn't hitting its benchmarks, leave! There are lots of other companies out there to join, including many publicly traded ones so you'll always have the full financials (and liquid stock).
If you do your homework and are serious about continually evaluating the company at which you work, you will not get screwed. Your time is the investment, and every 3-6 months you should re-evaluate whether the company is the best place to work. You don't owe the company anything! They need to keep proving to you, quarter after quarter, that what compensation they are giving you is worth you continuing to work there. Are you guaranteed to be successful? Of course not. Being an employee of a startup is risky, and you might make the "right" move that ends up not working out. Just from this article it seemed to me there were many clear warning signs this company wasn't all it was cracked up to be, and some employees didn't evaluate the company's trajectory properly and ended up getting screwed. It's a lesson learned but I'm sure many of them could have pointed out in retrospect where they went wrong.
And I'll also add that being a founder sucks, and being an employee is comparably much easier. First, getting companies off the ground is really really hard and founders have to do that themselves. As an employee you can look around and join a company that already is showing some traction, saving yourself a bunch of time and frustration. Additionally, as an employee you can and should leave if the company starts falling behind its benchmarks and you think there are better opportunities elsewhere. As a founder you can't really do this, you basically have to stick it out until the end.
So basically, being a founder isn't any better or worse than being an employee, they are different paths with different expectations, and each one of them has to be done with care to get the most out of it.
