Could be an opportunity for Czechs.

However, it is not necessary. Not all news sites are putting up the paywall and even those that are, they are not doing it for wire news (SME and Pravda are doing it for opinion pages, occasional "premium articles" and discussion boards).

SME tried it in the past and it was a failure, that did them more damage than improvements; this time they tried to cooperate among publishers and do it at the same time, but they still do not have critical mass. Most people that didn't drink the cool-aid expect it to fail again.

Not really, because almost all (if not all) large Czech news websites and press are owned by German media companies, and almost the same is true for Slovakia, so it's unlikely they would be interested in such competition.
