Your opinion on fake, made in China LEGO set copies

So recently my bro's relative bought him a made in China version of HERO FACTORY Furno:

It reminded me about my first BIONICLE sets which were also fake, made in China versions of visorak: Suukorak and Boggarak. Those sets actually introduced me to BIONICLE. On the fake visorak package I found a logo reminiscent of LEGO logo, so I googled it and found my currently favorite toy theme <3 (I was about 8 years old at the time).
I actually don't mind such versions of the toys as long as they are compatible with the toys they are based on. If you are copying someone else's work do it well :> (Droplet - a person who encourages to steal other peoples' ideas lol).
So what are your opinions ?
