High wages doesn’t mean they aren’t being suppressed

In fact, the higher the wages the more incentive to suppress, right?

This is the wrong way to look at it.

If the employees of these massive companies who illegally suppressed their wages hadn't done so then the companies wouldn't be so massive, and the employees would have more money and some of them would have had more resources to start competitors to the hypothetically less well moneyed giants.

This would have lead to a scenario where there's more competition in the market which means more innovation, more jobs for other people in tech, and lower prices for consumers.

Unfortunately this didn't happen and we're all worse off for it.

This. This is why companies win.

What do you think happens to YOUR salary if one big company, or ideally many big companies, have to pay very high salaries?

I'll give you time to study basic micro economics (supply and demand).
