Do you have any suggestions to combat this then EL? I don't know what's the best way to deal with it
Not really, TBH. It may be a bit of a cop-out, but it's probably unsalvageable now, and we can never return to anything remotely close to the song contest it started off as.
I think it's impossible not to have public voting now - it's pretty-much expected nowadays, and of course it brings in lots of money.
Besides: the rot set in long before big changes such as the introduction of public voting, or the huge expansion due to old Eastern Bloc countries.
My real beef is with the Eurovision organisers, who are very protective of the contest, and as a result are a big part of the problem. They were very vicious towards Terry Wogan: they really hated his criticism of the show and the voting bias, insisted he was wrong and actually celebrated when he left. The truth is however that it's got much worse since he left!
