Why can I use Halo Wars 2 add-on content without ever paying for it?

It's about the DLCs of Halo Wars 2, Awakening the Nightmare, the other campaigns DLC (to Marines or so) and all the leader packages like Yapyap package, The Lord Packet, Sgt. Johnson Package, Colony Package, etc…

I downloaded them on my one without having to pay them. - Now that I'm browsing for Halo games via Microsoft.com, I noticed that the DLCs mentioned above cost money, although I never paid for it - I bought Halo Wars 2 myself as a disk, second-hand and never a code redeemed for the game.

How could that happen?

P.s: the same goes for Halo Wars Definitive Edition (Halo Wars Remaster for the Xbox One) I also have it completely on the One, as a FULL game without having paid, and the game here in the browser also costs 20 euro

Did I miss anything here?

So

XBOX always shoots out GAMES WITH GOLD. There are often times DLC's drine. Maybe you downloaded it without noticing it. The other variation is that the DLC's were just a week free…

I wanted to download the DLC via browser (and same Xbox Live Account), and this time a payment method will be displayed. If I got it for free, no matter if games with gold, or free week, then there should have been "already acquired". - And because my One is standing around a lot and long offline, all games with gold products for the One will be blocked 24 hours after the last internet connection. - My console is offline for almost 1 month now.

Seems to be a really spicy mistake somehow…

Do you have the Xbox Games Pass? There's the Halo Wars Definitive Edition and maybe the DLCs for Halo Wars 2.

No. I'm only Xbox Live Gold member.
