What I am wondering that how much market share will Sony lose through all this? I will definitely not buy anything of Sony from now on. LOL. How many people will do that too?

Yes, your point is valid. But what really matters is that people are fond of PC gaming. And if they can enjoy PS3 games on PC, why they will go for another PS4 setup?

The article clearly states that among five tiers of emulators, only one is playable. That means the games must have errors, glitches, issues with the performance, etc. watch out for all these downsides as well.
