Technology demonstrator is any demonstrating the technology to get there not what science they did there. Indian space program will be one of a few delivery organisations for commercial and state bodies. It'll be good money. Landing on the moon is good for showing your expertise off since not many have done it safely and fewer been there lately.
They did it cheaply compared to others getting into the space delivery sector. They didn't crash like the Russians who've been there before nearer the equator which is easier to achieve. The Russians haven't successfully been on the moon since 30 plus years ago. Who has? China! But they lost contact with their rover.
Whether space race is more important than getting rid of the wealth gap that's another issue. One that I doubt America, Russia, China, the eu/ UK have sorted out yet neither. We certainly can't get on our high horse over wealth inequality matters vs space programmes.
The " Russians " have never been on the Moon. The Soviet Union have, their Rocket Scientists and Engineers were largely from Ukraine. 46 years since the Soviets landed on the moon.
The Chinese have been very successful, they landed on the far side of the moon in 2018 and successfully deployed a lunar rover, in 2020 they successfully launched a lunar orbiter and lunar lander which collected 1750 grammes of Lunar samples, took off and rendezvoused with the orbiter before successfully returning them back to earth. They're also planning a Lunar orbiter, lander and rover to visit the Aitken basin at the lunar South Pole for a sample return mission in May of next year.
