I would really like to see 2021 being a record year with
coming back to the contest and
joining and no withdrawals... coming after the turbulent Corona-filled 2020, which effected all countries, I think EBU should emphasize in their invitations to broadcasters that this Eurovision will be extra special, and stay true to the original ideals of Eurovision meaning a continent coming together after a crisis, and maybe even start up a charity to help victims of the Corona virus (both physical victims and their families, but also going to small and medium-sized businesses around Europe that will struggle as a direct economical consequence of this pandemic) with at least part of the income from tickets and the voting going to that charity. Maybe with such a concept, potentially they might convince broadcasters that might opt-out, because who wants to look like someone that wouldn't want to join a charity pan-European event? Maybe EBU could even be slightly more open to skip some of the costs for entering for a change.
I know, i'm being an idealist now, but I think such a Eurovision especially coming after 2020, would really be a good thing. While countries have their specific struggles, this is a pan-European one, and we will definitely need some healing after this as a continent, and Eurovision can be a force which can give some light and feeling of community that Europe will need.
