Based on what you said, you seem unhappy with some of the newer content. I can't completely fault you, but this is not anything new to VR porn. I am also subd to most of them and feel they come out with a good one every 6-7 releases (need more big titted models).
How does this benefit SLR? I don't know, but I doubt they are doing it just to say "fuck you haha". It's a business, and someone or a team said "We are losing out on money because of XYZ". So how does it benefit SLR? Money I would say is a fair guess.
But what you said shows it doesn't even matter if there is a cap on downloadable content because most of the newer stuff coming out isn't of interest to you. So how does this proposed download cap negatively effect you?
