Maybe you got that impression with his recent tweets, the fact is, he actually is the best India has to offer. The guy consistently fragged in this region. The problem is, India/SA region was never known for esports (Pakistan got success in takken, but nothing significant in fps games). If you consider the level of competition he had to face, it was the region which is to blame partially. It's the 13y/o kids who haven't seen performances of Indian teams on international stages before this in CS era who hyped him up. They were also a reason for the hate. Indian fans, specially those 13y/os were relentless and gave him hate on Twitter feeds, dms and insta. There has to be a tipping point and he just tilted.
If you just want to get the idea of amount of dumb valo fans India has, take a look at LFT posts of doma and ec1s. They were bought in by the 2nd most successful org in SA and didn't perform as expected. Their LFT posts are filled with hate and dumb tweets
