Others have done a good job at explaining what this is. Though, a quick tip.

If you’re ever unsure about what a component is, do a quick search for what those chips are. In this case, I see several Asmedia asm1061. In 5 minutes you should know more about that component.

It applies to most business.

1. You give a positive face to the market you’re in (Game Pass, Phil Spencer, pro-dev vibe, etc).
2. You buy chunks of the market (Activ-Bliz-King is a massive chunk), while saying it’s good for the industry.
3. You squeeze the company of its IP, while bleeding the market dry of money. All of which kills, or at least hurts that market.

Right now, Micro$oft is in the Extend phase.

Embrace, Extend, Extinguish.

There’s a couple of ways to block it.

1. Via an application Firewall, which will run on your PC. Safing’s Portmaster works on both Linux and Windows. Objective-See’s LuLu is a good Mac option. Both of these tools are free and open source.

2. If you know Unity’s IPs, you could block it in your firewall. I’m guessing you do not. Though, with a little work, it can be done.

3. If you can’t do either, you could at the very least block it at the DNS level. This will stop the software getting those IPs. It doesn’t really work if the IPs are already baked into the software, but that is incredibly unlikely in games. A great configurable DNS provider is NextDNS. If you have the know how to self-host a Pi-Hole or Adguard Home are great options.

There’s also ways to analyse that traffic, which I won’t go into here.

Lying about collecting that data, because they do (and I block it). Not lying, but backtracking on everything else.

Just gota get it up. Might be harder than it looks, though.
