Wasn't this always the case with the Dutch fans as well.
Barcelona and Madrid have a similar "win pretty or don't bother" mentality. Just ask Fabio Capello.
If I had to create a difference between the two, I would contrast the Brazilian "win pretty or don't bother" with the stereotypical voice of the Dutch soccer fandom as "play pretty or don't bother." Obviously both countries, or any country for that matter, seek to win, but there has been a certain aspect of Dutch soccer over the decades that promoted flamboyancy over pragmatism(ruthlessness?) whereas the Brazilians somehow could embody both. Funnily enough, the first player that popped into my head that exemplfies the stereotype of Dutch soccer is Socrates, a Brazilian. Yes, it's a game that they want to win, but it's also a show. And the show could sometimes take precedence, even on the biggest occasions. The Brazilians put on a show but they put on a show while they were putting the ball into the back of the net. That's not always the case in the history of the Dutch.
While there were many times when many Dutch fans were angry or felt ashamed of their national team, it was rarely over the style of play, but rather the drama(and that's putting it mildly in some cases) that followed the team to almost every major tournament. Obviously there was always the negative reaction after losing(74 was particularly devastating), but for the most part, they were lovable in defeat. Maybe moreso to outsiders, but I think its fairly accurate in the Netherlands as well.
Some of us have referenced the '74 Final because it exemplifies the stereotypes of Dutch and German soccer. The Dutch, having scored before the Germans even touched the ball, spent the next 20(?) or so minutes basically taunting and attempting to embarrass them on the ball(obviously political, personal reasons were a factor but it still highlights the show over the result.) On the other hand, the Germans kept their cool, stayed organized, and ruthlessly took the lead back. The Dutch never recovered.
Obviously, I'm playing with the general perception and stereotypes. The man that engineered much of the Dutch success in the 70s, Rinus Michels, was a pretty gruff and practical drill sergeant of a coach, but this thread of beautiful but not the bride runs through Dutch soccer history.
It's interesting because 2010 seems to be the point when both countries came face to face with teams that didn't embody the typical Dutch nor Brazilian team. I'd argue Brazil's was an evolution since the 70s, but the Dutch seemed outwardly to be more of an abrupt switch. Dunga's 2010 team was almost vilified before the tournament even started; the Dutch of decades ago would never have tried to hack Spain, but rather, rightly or wrongly(I'd side with wrongly) would have thought they could, or at least should try to, outplay Spain at their own game. I believe Brazil's was more of a conscious decision(I forget the World Cup(70s?), but they lost out to some stronger, fitter Euro teams and basically revamped their entire development and selection process to ensure it would never happen again.) The Dutch had a more quiet, natural evolution(toward today's more physical and tighter game) that really manifested itself in 2010.
