Not even once.

Ditto, made much simpler by not having a single Steam-based game in the first place.

I don't see any point to re-buying games on gog which I already have on steam.

Imagine you live in a house alone, then would you buy two television sets when you just watch on one of those ?

No, it's not logical.

Good actually. Don't have a lot of steam games so i only need to buy a few more here.Though it does annoy me that i didn't know about gog sooner than i am registered.Since i feel like i need to rebuy all commandos games here and star wars battlefront 2 and KOTOR.

Lmao, what? That analogy is so unspecific that it gives zero insight into the topic. You might as well just say "platform DRM is invisible to me".

Funny thing is that I told this story once for a dev based in rural Estonia and he, incredbly, said almos the exact same thing about drm-free; he has a cousin living in the woods, he brought his game to the guy, no internet access (I believe it was a matter of choice since, well, Estonia is a pretty tech country and stuff) etc etc.
Glad you liked it, dude ;)

I've done it, but anymore I just try to avoid buying games that require Steam. I make an occasional exception for particularly good Humble Bundles and set the payment slider all the way to charity.

Point is if you have already found enjoyment out of a product and continue to do so then why buy another one of it.
If you have a game on steam and played it many times till you got bored of it, you are not going to play it on gog again. So why buy it on gog. Waste of money.

perhaps you fail to understand this simple analysis, but that's okay.

Well, if that was phrased as a question, the obvious answer would be... because you're not bored of it yet.

I would (and do actually). Different rooms for each television is a very legit reason, unless you have a portable television set you can take with you.

The OP never stated it's about drm. If I buy a game on Steam and play & finished it, why should I buy it when it finally arrive here.

Personally I think the so-called drm-free movement has yet to prove anything, the Linux movement (which only make about ~1% of the gaming populous) has made more impact than the drm-free crowd. There is AAA games now coming to Linux on the day it's released.

If the game is good, yes.

Exactly. Too bad I fell for it. But now, it's over, I'm free! (DRM-free!) :P

If I can I do.

The are about 20 games I would really want here so I would never have use steam again.
For me it so I can play it again or let my children play it.

It's not like I buy games on Steam at full price, so I don't mind rebuying the ones I really care about for cheap.
