Just because an employee who worked 4.5 months with zero sales gets laid off? This is the problem with social media, now people think whoever makes the most noise is right. I've seen people getting fired for far less and they didn't make a fuss about it anywhere.
Nobody actually makes many (or any) enterprise sales in Q4, also in the video it’s made clear that the whole departments getting a culling. Which makes it a really botched layoff.
It is every company in the United States. They are not supposed to say anything to avoid getting sued. Watch similar videos. You will hear HR not giving any information because any word is a risk of getting sued.
