Well, RTVS truly is not doing well financially, for many years now. They almost went bankrupt at the beginning of this decade.
Right now they are going through a deep political crisis, so they have probably other things to be worried about than Eurovision. The management is getting rid of people who are not sucking up to them.
Quite a few people in the News department are leaving at protest due to censorship and propaganda from the management. Looking at SK/PL/HU state TVs, I am really happy that our state TV is free of such things.
Oh well, maybe in 10 years, Slovakia...
