As Lipko have said: The analogy is quite poor.
I don't have a problem with anybody buying Lego clones at all. If anybody likes to buy clones or bricks of other producers than Lego - no problem for me. What is a serious problem is a lack of difference in appearance between Real Lego Technic and its fake clones. Plus it's illegal to clone, produce, make money out of products that already have its own style and brand. Plus some people are still unaware that such fakes with poor quality even exist. This all makes that all these Lego clones, fakes become a serious problem for Lego second hand market.
For me decoo, bela and other crappy companies may produce its crappy bricks - no problem for me if they do not copy LEGO's ideas, styles, bricks, if they just make their own, unique, crappy bricks that are easily recognized and differed from Lego.
And here I am serious: I think Lego should run a case in court against these companies that produce fake lego. Just because Lego customers, children, fans, Afols as well as Lego itself as a brand and company lose out of this sick situation. Someone should teach these cheaters a lesson.
