I prefer to think of all these boards as alternatives, there's the usual tribalism around Beaglebone Black, Pi, Orange Pi, Banana Pi, Arduino etc.etc. and they all have a place, the main thing Pi has is an incredible community and the manufacturers are very active too.
I once got lectured about how Pi wasn't good enough because they were being bought and used as media players and that it was sad but to me that's an amazing advantage, because those people who know nothing about Linux, programming etc. have contributed to a huge maker community and helped pay for further development, it's also sparked a huge number of clones, alternatives, all sorts. I've spoken to all sorts of people who are tinkering with Pi and Linux because of Pi and other boards.
If the popular, cheap boards encourage people to hack (classical use of the word) hardware, software etc. then it's all good as far as I'm concerned.
