True.  Still, this is a one dimensional statement. 

Taken in context we are all in competition for the same revenue source - mining subsidy.  It is every participants responsibility to

1)  Understand their business/market.
2)  Make informed decisions.
3)  Protect their interests.


So, we shouldn't be surprised if miners challenge Bitcoin mining hardware vendors in order to understand/criticize vendor's business plan/practices.  Ultimately, "hobby" or "pro" miners should always be vigilant to monitor any potential market competition and take whatever action available to them to ensure their survival. 

It's surprising and sad that the "mining community" lacks sufficient cohesion to form a semi-formal mining association to represent interests and provide leverage in cases where vendors might threaten their existence.
