I guess "Do the right thing" means that robbery is fine so long as you choose the right victims.

The theft by google and apple had effects broadly in the economy, far outside of the colluding companies.

Regardless of how much the employees were being paid, CEOs colluding with each other to not recruit employees from each other was a blatant violation of US anti-trust law.

Perhaps, but "first world problems" can still kick off other problems for everyone else down the line.

If you hold down the wages of of the top 10% of laborers, then the next 10% have a harder time getting raises too, etc.

In addition, if those systems of collusion become established, they're a strong profit-motive to gradually expand how many workers are being harmed.
