The article states exactly what I surmised - that Israeli state agencies produced and broadcast the ads I saw, in the US, on various platforms.
The EBU says it's not against the rules. I think it's time to make a rule.
I think the global voting issue and the potential to vote 'strategically' could be mitigated by weighting the votes coming from sexretly and randomly chosen countries, or by taking an average of the jury and public vote and leaving that as the final score.
Weighting random countries' votes could look like each vote from verified accounts in five secret, randomly chosen countries on Eurovision Final night (for example, Cyprus, Australia, France, Iceland, and Lithuania) counting for two votes and everyone else counting for one. The chances of manipulation of the unknown randoms would be small (never zero, but small).
Overall, though, I think opening voting to the global audience is a huge part of the issue.
In particular, I think opening voting to US voters is problematic even from the pov of musical taste.
