China are doing this with Harmony OS because of the huawei ban i agree being so reliant on US companies means we will never develop these technologies inhouseIf these guys seriously want to do what they say they want to do and dethrone big tech in India, they should start by supplanting Android with an Indian version of something like Postmarket OS. Include it as a medium term agenda. Although it will cause slight consternation in Smartphone makers because mobile Linux distros are not going to bloatware the $hit out of the smartphones and allow them to work for 10 years, thereby decreasing the number of people wanting to replace their smartphones with newer models frequently. But it will surely help in supplanting google because people will prefer it over Android after a marketing campaign explains bloatware to the janta. Someone should also design an Indian search engine.
YouTube will be one of the most difficult things to replace.
