Those countries are not part of the EU, not sure what point you are trying to make.
This was not negotiated as a friendly trade deal as done with Canada, US, Swiss etc. It was clear they were doing something the EU doesn't want to make an example off. Tensions from both sides.
Edit: Aha, I understand know you mean they could have gotten the same deals as them. If you have sources for this, please share, but as far as I know this is not true. Take for instance this excerpt from the Financial Times:
"Slides presented to EU member states this week by the European Commission suggest it is looking for something far more sophisticated and hard-hitting for Britain. If Brussels has its way, the system will govern not just the two sides’ future trade relationship but several other partnerships in areas such as security and judicial co-operation, joint research, and aviation.
One of the key motivations for the EU is to avoid replicating the unruly jumble of agreements that govern its deep relations with Switzerland — whose population in 1992 rejected a proposal to join the European Economic Area. The two sides have subsequently built their relationship up over time, resulting in no fewer than 100 agreements governing their relations.
