It's not just that. MBI media used to be plain awful, both CD and DVD recordable media that is, quality and compatibility wise. Things have changed over the last few years, and the overall quality, and most importantly, compatibility of MBI media has improved dramatically.
MBI's main problem a few years ago was the poor firmware support from the drive manufacturers -> unoptimised write strats in combination with mediocre (at best) disc quality lead to horrible burns.
Today, MBI media is one of the better alternatives for budget-oriented consumers. As you may know, tests of the German magazine c't showed MBI DVD+R media to be of good quality, and very resistant against climatic impact.
