What's up with the non existing demos on Steam?

 So okay I only noticed this cause I kept getting a 'no license' message when I tried to download a demo, I took a rando game to show you what I mean.

When you click the category 'DEMO' you get a frontpage for all playable demos on steam, and if you hover your mouse over it, you get this. My steam is in Danish, but it does say 'install demo' on that green field/button, and normally you'd be able to click that and it installs the demo.

But if we click it, we get this message, which says 'An error occoured when starting this game: no license' - and you can only click 'close' and you're taken back to the Demo front page.

And of course you have no license, it's a demo for fucks sake.

So again my Steam is in Danish, but it looks the same, so can you see it?  there is no 'download demo' button on their store page - the green button there says 'add to wishlist' and that is it.  Which tells me there IS NO FUCKING DEMO TO DOWNLOAD!!!

If there is a demo it will look like this on the game store front, there is a green field and it says download. And sometimes it's in the side menu, and "hidden" as in the button is not green but dark blue, but it still says 'download demo'

I had to roll out my inner Karen at the Steam community tab, cause it actually bugs the fuck out of me.
