The winner wouldn't get to host next year tho'.
It's one thing to wonder what might have been, but a whole other matter to know you
won but get jack shit to show for it.
A pat on the back and a mention next year maybe, but the whole point of winning, putting on your own show, is taken from you. Maybe for a country with several wins under it's belt already, or a country that's won in the last 5 years, it wouldn't be a big deal. But imagine Lithuania or Iceland getting their first ever win, something that might not happen again for another 20+ years.. and it simply goes to waste. To me that seems incredibly demoralizing.
At this point, I think they'd be better off not knowing they would have won. What they could do perhaps would be not announce the winner, just top 5 or something? That way you'd get the knowledge your song did well, but not the bitter feeling of having lost your hosting chance.
Not sure how much work is involved in organizing a televote anyway.
If it requires lots of people, it might not be doable under current conditions. An online vote on the other hand seems very easy to cheat & manipulate.
