Firstly no one is ridiculing the aircraft as it yet has to enter and prove it's operational capabilities with squadron service, however it's the manner and mentality of Indian members and public that leaves much to be desired and please don't just blame shoddy journalism for this since it's only performing it's duties by feeding the Indian habits.
True that ISRO has made strides in it's field but that doesn't mean this was also a priority for Pakistan. Each country has it's own ambitions and goals. Just yesterday i was reading that in the last month alone, 116 Indian farmers committed suicide, how many died in Pakistan...Zilch.....
You see there are countries who go about quietly doing their business and there are those who like to make a song and dance about every minute detail. India seems one of those as it seems to demonstrate this at every opportunity, be it in some domestic product an international exercise or dealing with neighbours, Indian tend to box above weight only to be ridiculed and humiliated afterwards. Coming back to the subject, it's been in making for three decades, it hasn't even entered the squadron service yet, but we never hear the end of it, from being next generation to becoming a major player in the market. After it's first appearance at a second tier air show, you guys started chest thumping and ridiculing the JF-17....which has appeared at some half dozen real air shows. You see India in some ways reminds me of North Korea, who start gloating every time they turn a screw and make believe they have conquered the universe.
