You can expect an argument to stand the test of time, but not a material example, because the speaker is always someone in his circumstances. I'm not saying anything for or against the argument, just that the foundation of your disagreement isn't too solid.
I think ghandi speaks much more from a tone of trying to make you think differently, not necessarily being right or wrong, but making you accept or reject him by making you contemplate for a moment his perspective.
In this case you reaffirmed your view of the world that technology is a vector of freedom, but what is the circumstances of that technology? Because when you think of ghandi as an Indian, and that Indians suffered a humanitarian crisis in the hands of the English empire, I can't help but wonder if the colonizers just created the poison than sold them the medicine.
So from his point of view he's right to reject technology that are colonization instruments, but if that same tech would otherwise take place in the world from the needs of the people, then it would be an acceptable technology to adopt. And this argument is timeless, because how many current tech, the social networks, the language models, are actually being used as colonization tools today, by influencing elections or by spreading misinformation? We don't need to go that fast, not when the price to pay is our freedom.
