Working retail and food service taught me even if you literally give something away for free, people will still find a reason to complain. "Free hamburgers today" But I don't like hamburgers. "Today only, get a free 6 months to Spotify if you sign up for something else" But I don't use Spotify.

Just, okay? Like fine it's not for you, it doesn't matter, it's free.

I think part of this is, if later there are takedowns of these games, many people will experience them being removed from their ownership.

They do general giveaways all the time, this one is specific to a cause and is therefore flavored as such. There's a discord bot I use to track giveaways from GOG, Epic, and Steam, there is always a giveaway happening at pretty much any given moment from at least one of them. You could look into that or similar if you just want free games.

That completely misses the point of this giveaway. Even ignoring that, these games are being donated by the devs. I'm not sure why a studio not affected by this at all would donate their game fighting this (I know a few might on principal but still)

they've given away so many games, where were you

That's a good idea. Let's give obese people sandwiches to raise awareness for starving kids, too.

I'm in the same boat as you. Except for house party. I will be playing house party.
