It means what it says that there are some issues with linking your account, namely that you don't have the required amount of subscribers or watch time in order to join the network.
Your channel only has one public video. Freedom! needs you to have cohesive content without copyright issues. Oh and thanks to YouTube you also need 1k Subscribers and 4k hours of watch time per year to join a MCN like Freedom!.
Unfortunately under new YT rules as mentioned above no MCN or network is able to allow you to join without the required views and subscriber count. You can still apply to join via the website, however as mentioned previously your application will be on hold until you hit the requirement.
