You have asked a good question about how what is there to stop it if things worsen , first would be the Judiciary as it's strong and trustable as it's kept out of poltics as it there are more number of supreme judges and the selection process of judges is better unlike Usa where judges are selected by presidents and are fewer in number thus more controllable. Indian judiciary is good and maintains a lot of power.

When Soviet union dissolved Russia inherited a very weak justice system which allowed Putin to seize power and keep himself very strong. The difference between the powers of the judiciary in the three pillars is much better in India.

Second would be the diversity , the linguistic , cultural , regional differences in India is so much that it's hard for anyone group to dominate without extreme resistance. On the other hand Russia is mostly Russian speaking. Russia is diverse as well but still majority Russian. It's very hard to go Russian levels in a country with no clear majority group.

That's why it makes a person look stupid when he/she says there is a clear downtrend and things could go bad as Russia. It ignores alot of stuff which is different and a lack of clear trend to either direction. I really think after this explanation you're not gonna say stuff like there being a downtrend and compare or bring up Russia because that would be make you look ill-informed and not capable of understanding the difference between trends and consistent issues. If you think these issues could worsen to Russian levels or hybrid regimes levels then read the top portion of the comment again otherwise it will make you look dumb.
