From some quick web searches, it seems to me that India did many of the things you mentioned. I'm not sure if they did all of them, or to what extent they did each one - understanding that precisely is probably not possible without being involved in those particular actions. But it doesn't seem to me like they did nothing.

Do you think India downplayed the pandemic? I don't get the sense given that they did building by building lockdowns and have police patrols ushering people back into their homes. We should keep in mind that each country is different - they have different population sizes, city densities, wealth levels, infrastructure quality, Internet access, cultural priorities, and so on. China is not India - it has an authoritarian governmental system. Taiwan is not India - it's small and rich and is an island. I'm not sure these comparisons are fair.
