Would you also go into a grocery store or Walmart, or wherever and take some items because you figure thay cost too much?
LOL, no if it "cost too much" then it cost too much and I just don't buy it and look for it somewhere else... like maybe ebay.
Totally different... I am buying a product, not "stealing a TV". I am not the guy selling them. Yes I am supporting him by buying from him, but that's the way it goes.
I feel for you putting in all the work and having it copied. I have no idea how much $ goes into R&D on these chips, so your price could be entirely justified. But I'm a cheap bastard and if I can find a deal... not ashamed of it. Not going to be guilted into spending $200 more.
BTW I have had products copied before and sold on ebay for much less and was actually forced out of selling those products due to costs. As I said above, that's how it goes.
