One thing to note is that most top-flight Irish football matches are played on a Friday evening, in a move to reduce the competition with those other sports to some extent.
League of Ireland attendances did initially increase when summer football was introduced, but have dwindled again since the novelty wore off. The main complaints tend to be the same as ours, though, rather than anything to do with the Friday night/summer experience-- too expensive, poor quality entertainment, and unpopular league format (top 10 teams playing each other four times a season).
You certainly do still get the odd postponement in the latter stages of the season too, there were a few around October/November last year due to waterlogged pitches.
