I'm not sure why this MTC exists? is TechNet forums being replaced ?

Not first time discussion. I like the best answer in this thread https://techcommunity.microsoft.com/t5/SharePoint/Am-I-in-the-right-place/m-p/47767/highlight/true#M4550

I guess all these forums will always be overlapped, we may speak only about trends and intentions, which forum goes which direction
