> Half the country or more just doesn't work or do anything else when there's an important match anyway.

This is completely false. In the first half of this LaLiga season, the most watched match had 3 million viewers: https://barloventocomunicacion.es/informes-barlovento/el-fut... Spain has a population of almost 50M. So the most viewed match was around 6% of the population.

I’m not sure what makes you think you “know Spain” enough to throw this kind of ridiculous claim around, but please inform yourself.
