I'm not sure where you get your information but YouTube only has issues with MCN's that skirt the rules or don't provide the service that they claim that they are providing.
As for the OP, he did not state that he requested to leave in a timely manner. He only stated that it's been 2 years and he wants out.
They never have. I thought that was a well known thing. That's why they have so many rules on it.
Another note, stop quoting one thing, it just makes you look like you are bending my argument to your will and really grinds my tits. Especially when you go on to say more and especially when I made an important point that you have skimmed over. He said he tried to contact them and they haven't replied to him. He's said that he has contacted AS HE WAS TOLD TO DO SO, he has said they haven't replied so I genuinely do not see where you are coming from. Is it an inability to read? I'm confused now. He clearly states that in his first post. Sounds to me like he has upheld his contract, and we have no information to say any different. This would be easier away from American rules as rolling contracts are a thing of the past everywhere else and we have options to cancel a contract we have signed in to between 14 days and 28 days, but American law is archaic. Either way, we have no information on it being a rolling contract so it would be wrong for us to assume that there was a rolling contract as all the details we have provided are the fact he had to contact after 2 years to leave and has done that.
Having a quick look into it through Google though, TGN does not operate on a rolling contract . In fact they don't do lock in contracts anymore either. So if he does what it says below then he can have no argument.
Anyways for OP without any judgement on you or your channel, straight from Youtube.
"If you're an Affiliate channel and have fulfilled your contractual obligations to your MCN and want to unlink from your MCN content owner, you can request to leave by clicking on the
Request to unlink button in
Channel Settings in Creator Studio.
Important: If you leave an MCN, you need
set up monetisation and
link your account to AdSense to continue earning money and getting paid."
Exactly as I stated.
It goes on to say
"Best practices for MCNs
All MCNs are responsible for providing value to their creators by following YouTube's best practices, including:
- Avoiding spammy, misleading language to recruit channels to join an MCN.
- Clearly explaining in a contract the services and levels of support provided.
- Acting in an honest and transparent way with respect to services offered and contractual obligations.
- Onboarding and releasing channels in line with their contracts.
If an MCN doesn't adhere to these best practices, they may lose account features and monetisation. If you believe that an MCN is not following YouTube's policies,
contact the Creator Support team."
So the best way to try and get round it and make it a Youtube issue is to contact them saying they are not upholding Youtubes best practices as they aren't responding. This is not acting in a transparent manner. Also they are not releasing your channel in line with your contract, so link this to Youtube and make them realise it is in their own guidelines.
I would send a copy of this to your MCN too to make them realise you have took it further. Most MCN's don't believe you will do and do not want the trouble so it is kind of like strong arming them. They advertise as the best support on Youtube and 24/7 support so they aren't being transparent.
