I am not entirely sure that is "profit focused". It's profit on a real world situation, you said it yourself - less QA work which makes it able to release faster. They are only taking advantage of that fact. They would have to focus on not profit for it to happen any other way.
Because they know most PC gamers have at least one console as well, and they'll buy it on release at full price, and then again on PC for the better gaming experience.
Cause idiots literally go out and buy a console , then get the game there, then get it again on their PC in 18 months and literally foam at the mouth all the while.
Remember these publishers are in an ouroboros style circle jerk with console makers. They move without giving a tug, and never move without getting a tug. They go console exclusive to boost console sales in the first year, use that time to continue to improve the half baked game, then release on PC with higher specs to reap the PC fans marveling at the higher graphics.
