That's fair, as it's your preference. It's my preference too to use steam just because it's where I have the most games and I like keeping things tidy and in 1 place. Though it's not an ideological stance, which "refuse" leads me to believe. I'm genuinely curious about the reason an adult would take that position. Last time I asked (a couple of years ago) on Reddit I didn't get, ummm, mature responses.
If there is a game I'm interested in, I'd use whatever is cheaper/available for it.
