I called Unifi helpline to verify this no CAP limit twit but found that it was load of crap. Its probably some marketing crap to bluff people into signing into their 2 year contract. Plus I checked the website was updated, but the limit is still showed on the packages.
The operator said that no cap limit is only for local content. International content still follow the original cap limit. I tried to argue with her about the twitter twit but she was very confident that the information she gave me is correct. I really want to sign-up but 60GB cap is just doesn't make any sense. whats the point giving us a ferarri but with only 60 meter worth of petrol to drive...
