It doesn't even really need to be India, it could just as well be stolen by someone in your country. The vast majority of open source developers don't have the time to invest into copyright protection. Trying to actually enforce your license is signing up for a years-long nightmare of wasting your time, energy, and money dealing with the legal system for, in the end, no real value to yourself. If you release something as open source, you pretty much need to be ready to accept that your license is meaningless when it meets contact with reality.
This is all the more true with LLMs existing now, which are freely used to launder copyright licenses. Maybe in the past GPL would've made Microsoft or Google, at least, think twice about using your code, but now their developers will prompt GPT to reimplement your code.
