Market does not decide if an OS is good

There seems to be a trend with people claiming stuff like, "WP sucks no one is buying it". I'm not sure I understand this mentality. Market/sales don't decide if an OS is good, YOU DO! If market made my decisions I wouldn't dual boot Linux and I definitely wouldn't like Pearl Jam as much as I do (after all Justin Bieber sells more). Where did this come from? Growing up, technology and computer stuff was always kind of a fringe hobby. People really took a lot of pride in that. These days, it's the opposite, if it doesn't sell, it sucks. Who cares, if YOU enjoy what YOU are using isn't that all that matters? My only concern is that Nokia/WP sells enough for them to continue making Windows Phones, because I like them and want to continue purchasing them...
