Except both chair is priced at 0$.Let me put it this way. Imagine if you make a chair that's full of splinters and then you try to sell it, of course putting it next to proper chairs. Do you think this would be worth anything?
This translation is worthless because it's worse that what would be put out later by the group that translates this manga, it would literally be better for everyone if the person who did this translated any other manga that isn't being translated.
People are free to choose one of them, or both. Of course everyone will "take" the good quality one. But did the carpenter who make the good chair loss something?
If they loose motivation and stopped making a chair, just because someone make a bad chair in front of them... Well that's too bad...
It might be worthless, but it's def also harmless, and at least they're trying.
Did just by seeing the bad shaped chair, can hurt your eyes? Just train your eyes by looking at mirror 1 hours a day then.
