Yeah you do hear the minority speak the loudest. A lot of people fall into that sort of "middle-ground" category. They are indifferent to most things and don't care basically. But in the internet age, it has become much easier for smaller groups to be the loudest.
Also, the Pokemon vs Yokai Watch seems to be somewhat of an extension of Pokemon vs Digimon from the 90s. But Yokai Watch is unique in that it actually was beating Pokemon in Japan for a while. It's a shame that Yokai Watch received the hate it did, cause it has a lot of merits that Pokemon can learn from. But when something is so popular and big Pokemon, the fans like to write-off any potential alternatives.
