If watching this much videos from such large array of services is that important for a family I am sure they can easily cut down on other leisure and entertainment and come up just fine.
They dont need to wach "much videos". The argument is about "specific movies and series".
And for that, there are three options: piracy, pay many services, constantly juggle sign ins and sign outs.
A lot of spanish people live with less than 1000€ a month. You can barely rent a 2 bedroom flat in many cities with that.
100€ for leisure and entertainment is already a huge sum of money when filing the tank of their cars to earn their salary cost them 2 to 3x 80€ already.
