How's this a fyigm situation? He left 5 years before this particular thing happened, he had no say in it.
Now if he has actual need for these employees in his new company, I could see him hiring them there, but his new studio is in California and those employees were sacked in the UK, meaning they need a new job in the UK to keep living there. He also currently has fewer employees than the amount that R* fired. That's how small that shop is.
His brother, however, is still an exec at Rockstar. He, along with the rest of R* and Take-Two leadership has a lot to answer for.
