Quoting lines from old articles won't change the truth, no matter how much you want it to.
Tejas was in its prototype stage when these materials were used, however now is a totally different story.
Alloys for Tejas-Mishra Dhatu Nigam Limited (MIDHANI)
MIDHANI - Superalloys
Composites-Tata's Advanced Materials Ltd (TAML)
Livefist: State Agency Busy, Private Industry To Build Composites For Production LCA Tejas
Majority of the area of the airframe is composites and the composites are made by TAML
so think it out for yourself if only 30% of the Tejas airframe is indigenous?
Tejas - Technology - Composite Materials
ejection seats-Armament Research and Development Establishment
DRDO
Only the HMDS system is provided by Elbit the HUD is done by CSIO, Chandigarh.
Mission Computer-The hardware unit development was done by ASIEO, Bangalore and software design & development by ADA.
Control & Coding Unit (CCU)-The hardware is developed by RCI, Hyderabad and software by ADA
Display Processors (DP) of LRUs in the Tejas-ADE, Bangalore
Mission Preparation & Data Retrieval Unit (MPRU)-LRDE, Bangalore
And most of the USMS Electronic Units also done by DRDO subsidiaries

And your link also says this
"China has a long-term requirement to replace its Xian J-7 (MiG-21) and Shenyang J-6 (MiG-19) in the attack role, with the LCA providing a potentially attractive option."
This really discredits Tejas

Lets skip every thing even today, the IAF claims that the complete home grown and total indigenous aircraft is only 60% indigenous......

As per Dr.V K Saraswat Tejas is 65% indigenous

Thanks for the laugh, such incompetence that we are having
batch I completely operational adding further claws to it in a poor economic state,
while India having US, France, Israel and Russia at its back door is 17 years late already and hasn't put 1 fighter in active duty ....
remarkable competence of India i must say
Laughing at something only you understand is just plain foolishness, let us not forget that JF-17 has even lesser Pakistani input than what India has on the Su-30MKI.
The
main reason for the long development process of Tejas is the sanctions imposed by US especially the one in 1998Tejas was dependent mostly on Lockheed Martin's equipment, after the nuclear tests US govt. forced lockheed to terminate the Tejas program and every data on wind tunnel designs, simulators et cetra were withheld and not allowed to take back to India, thus DRDO had to start anew.
According to Dr. V.K. Saraswat sanctions were in actuality never removed since 1988, the window for development of Tejas opened only in 2005.

Thus despite of the help that DRDO recieved, it had more adversity in the Tejas development.
Unlike JF-17 which doesn't even have a quarter of Pakistani Input, the Chinese did all the work for you.
No sunny boy, the reality is you cant face the music, when you see your own air marshal level officials exposing the truth to you, however lets for one second assume LCA Tejas is totally and completely indigenous .....
DOES THAT CHANGE THE FACT IT STILL HAS ALOT OF TIME TO GO BEFORE ITS PUT INTO SERVICE EVEN AS PER OFFICIAL PLANS (2015)
while the incompetent Pakistanis would be by then improving and continuously building on their first experience and looking at advanced versions of the basic model ... even in the times where pakistan's economy is in its worst state ever
And no one has ever said that "Tejas is totally and completely indigenous", you are the only one who is trolling so.
And how far has JFT evolved into Block-2?
Wasn't the JFT Block-2 to be inducted in mid 2012?
It seems like its another way round, you are the one who's itching coz your bubble's bursting.
And no matter what you say your most amazing JFT is still not inducted in PLAAF.
