Yawn.
It was not right of netizens but targeted harassment and trolling to call Rihanna and Diljit Khalistani and separatist just for tweeting for farmers. You cannot call someone secessionist just because he or she supported a protest.
There was NEVER any perfect image of Bollywood as you claim. Magazines, papers and media always kept explosing the debauched lifestyle, affairs, denying due credit and salaries to employees, philandering, casting couch, manipulation, buying awards, attempts to sabotage films of rivals, drugs, alcoholism etc in celeb lives and industry. Infact films like OSO, Fashion, Heroine, Rangeela themselves exposed dark side of glamour world. So do not act like targeted harassment and propaganda by a party exposed dark side of Bollywood. They did that drama to hide their failures in handling COVID crisis and punish stars who are critics of ruling party or have different ideology or are kids of stars who have been critics of govt at some point.
I know stars are paid to campaign for parties. It is even a BIGGER shame that same party that pays stars to do propaganda for it, targets the same industry whose help it seeks to push own ideology. Even worse to target those very people who you pay for lending their services to you.
The politicians and media are no saints themselves. They have their own #metoo moments, bribery, corruption, hate crime, murder cases and other crimes besides blackmailing public figures or being involved in drugs themselves. Who can forget how Rahul Mahajan was exposed for drug abuse and same party spokesperson said 'jawani mein aisi galtiyan ho jati hain' in 2003-04?
Underworld links eh? So who stopped govt and agencies from investigating those stars and producers and taking legal action against them? What stops govt from taking action? And why are same underworld linked stars campaigning for this party? Anil Kapoor was clicked with underworld don (Dawood's brother). Why same Anil is used to campaign for Kirron Kher in Chandigarh?
Do not just say things for the heck of it unless you got evidence or intend to take action to clean the mess you allege. Otherwise it is just abuse of power to intimidate and harass those who you want to either keep quiet or blindly take side of ruling parties.
