But they did mention that community servers would be able to pick which Anti Cheat they wanted to use?

As I understand, there are three tiers to this:

• Official servers will use FaceIt exclusively.
• Servers rented from official partners will have the choice of FaceIt or EAC.
• Community-run servers will only be able to use EAC, and won't be hooked into the global progression system.

One of the many problems with FaceIt is that the server-side component is not allowed to be freely distributed, which is why community-run servers won't have the option to use it.

Personally, there is no way I am buying this unless if they reverse their plans to use FaceIt.
