Such a massive publisher that they've never published a game outside the Witcher franchise...
In the context of actual mega publishers like EA and Square Enix, they are the little guys. Even something like Bethesda, which is obviously a tier below those two is still well above their reach. So when they spend ~4 years making their magnum opus and betting everything on one game, it's gratifying for some to see it pay off so well. They were nothing before Witcher 2, that gave them the resources to make Witcher 3, that's given them the resources to make Cyberpunk. Seems like an easier studio to root for than most of the AAA industry.
And I'm not one of the biggest Witcher fans out there by any means, I had multiple games I liked more in 2015. But I did think it was a great game and I could tell how much they put into it through the sidequests, which got more care and good writing than most games main quests.
That's like saying Valve is only about Half Life and it's derivatives (Portal, CS, TF). CD Projekt also owns GOG, which makes up the bulk of their revenue (about $125 mil USD). They're just as AAA as everyone else.
