There's quite a debate about clones. Lots of different views on the subject. Here's my take on it. So the following is all personal opinion.
When I first started vaping, I thought I would never get a clone. Having different hobbies in life, where clones really hurt the industry, I absolutely would never buy anything that was a clone and even reported the clones I found while browsing to the forums I frequent, so others could stay away from them.
However!!! In vaping, I have actually found the opposite. Because of the nature of vaping, this is more than just a luxury hobby for many people. It is helping people quit smoking. The existence of clones means people can vape quality devices for prices that are within their budget range. And it helps them stop smoking. That, to me, justified the existence of clones.
Another reason is availability. As a knife collector, I don't mind waiting 5+ years on a waitlist for a specific maker to make me my custom knife. As a vaper, however, I don't want to wait any length of time for a device that is helping me get off smoking. And for me personally, if I just pick up whatever is available at the time and settle, I don't think it would have swayed me off cigarettes. So buying a clone, while waiting for an original device is something I feel is working for me.
Now the big pet peeve of mine. Like many others, while I have learned to appreciate vaping clone devices, CLONE VENDORS: STOP PUTTING THE LOGOS ON YOUR DEVICES!! I would rather you identify your clone and leave it branded with your brand or leave purely sterile, but don't etch the original maker's trademarks and emblems on it.
That's my rant.
