Because the free games here are better.

Because they don't have those games here.

because steam owns 90% of the pc gaming market
and has as such a lot more crapware

most of those "free games" are either garbage or pay 2 win ware

Because GoG is not a Steam. Here you actually buy games, not renting them. If you ever decide to leave GoG, you will keep your games.If you decide to leave Steam, well, you may keep your keys..

Because the world is flat.

Simple - GOG knows quality of games that can be worthy given away for free.

Steam's idea of freebies? Oh, a key to a crappy $0.99 title that's crapware, buggy, broken and ultimately not fun.

Yeah I think I'm good with GOG and even Origin's freebies.

Because most of those "free" games on steam have dlc that are either damn expensive or uncountable many but cheap?

One word: Plastics

Some people don't quite grasp this concept.

I even had a nephew ask me, "What do you use to install the game"? , "How do you launch the game"?, "What about backups and saves"?

Scary stuff right there...

Sounds like people in California talking about the rest of the country. :P

"How do you get food?"
"Is it hard living without electricity?"

Sorry, I don't quite understand the meaning of this phrase. Could you explain it to me?

Simple. GOG isn't Steam or isn't owned by Valve. They can make as many free promotions as they want with whatever games they want to go free. That and like someone else said above, they prefer to give away a quality free game over a crappy broken game.

Anything east of Lake Tahoe. :P

Sadly I know what you mean.. We're all living in Harrison Bergeron world.
e-cigarettes, cybersex.. this won't end well..
