back in the days I used to buy mostly Monster cables, but I completely stopped patronizing Noel and his company after he got gun happy with so many "trademark oppositions" and a few lawsuits that had not merit. he actually did some damage to a couple of small companies that were trying to us "Monster" as part of their brand name. I remember reading about it and getting disgusted. He was a "Bully". It became so much of an issue that he actually had to defend himself with a response in Audioholics. The only thing that stopped him was his sound defeat after he sued his ex business partner "Beats". He was ordered to pay millions of dollars. The funny thing was, this time the suit has nothing to do with patent infringements.
Same thing with Sony. I stopped buying Sony products after the heavy handed approach with lawsuits for copyright infringement the company started using geared toward young kids and their parents. It caused a very negative market response. They should had geared their efforts toward the big and medium companies and individuals that were ripping them off with illegal copying of their music, instead they went for the jugular of some kids. that was pathetic.
