Apparently some lawsuits have started on Sony’s potential price-fixing of all games on their platform since they’re now the only retailer. Before anyone gets excited, these are probably going nowhere, but it’s neat that something is happening. The idea seems similar to the Epic vs Apple/Google lawsuits.
The only thing I am challenging is your claim that console has ceded market share to PC.
“Market share” has a defined meaning. Revenue for console and PC have both increased, one more than the other, but neither have gained any market share.
Maybe you just used the wrong metric to illustrate your point?
