> ISO (Incentive Stock Options) are one of the biggest scams of all time and you’re financially illiterate if you value them more than zero. They are carefully designed by venture capitalists to screw employees

Given the number of millionaires and billionaires who can credit ISOs for their current wealth, I think that's too broad a statement. At the end of the day, a well-run company that can eventually go public because they have a strong business can be worth joining and the ISOs can be worth something someday. Admittedly, many will not, but if you pick the right one, you could do well.
