The issue is not legal names, who has what registered, etc. It is a community issue.

The community thinks of EOS Sweden as Eric and his team.

It would be in good taste for you to change your name. All you are doing by keeping the name is asking for an arbitration case once the chain launches.

My advice still stands. It is best to choose a different name since EOS Sweden is so closely aligned with Eric and his team. If you pop into Telegram and ask who is EOS Sweden, people would say Eric, Vahid, and Sean.

You are still new to the community so I would think there is plenty of time for you to change your name. A name is not worth damaging your reputation in the community.
