Why was Virat Kohli fined in recent IPL matches?

Iti

Virat Kohli fined 50% of match fee for IPL Code of Conduct violation during RCB vs KKR match. He argued against umpire's decision after dismissal. Dismissed caught and bowled off a full-toss, Kohli felt it was a waist-high no-ball. Ball tracking showed it would've dipped below waist height. Rule 41.7 states any delivery above waist height is unfair, regardless of injury potential. Umpire upheld decision, upsetting Kohli. Kohli expressed frustration to umpire while leaving field.

But these fines are likely deducted from the players' match fees, so they are still meaningless, as players earn more from auctions and brand endorsements.
