I think I can understand why that's happening Rapham0n.
It makes little sense at first, because it's twisted logic, but if you look closely at the topic from a larger point of view, you can finally understand how it makes a bit of sense.
For home console there is still a market for physical copies, and while this market is slowly dying with each passing day, there's a whole system that lives on it, with people working and getting salaries thanks to that.
Distributors, physical shops, etc etc.
This hardly happens for PC, the market is practically dead for physical copies, and given the lack of this important aspect digital copies can be sold for less without "ruining" any existing system or creating major issues.
There are many other aspects (like higher piracy on PC rather than consoles, etc etc) but I feel this is one of the big ones.
