Please note that verdict does not say that Karnataka should release 419 TMC to TN. It only says that TN should get 419 TMC out of total of 740 TMC available in Cauvery. For TN to get 419 TMC, Karnataka needs to release only 192 TMC. TN gets rest of water from Cauvery water capturing area in TN itself. This is 13 TMC less than tribunals' interim award of 205 TMC.
Out of 192 TMC that TN gets from Karnataka, it has to release 30 TMC to Kerala and 7 TMC to Pondicherry.
So, unlike the media projects, verdict is not against Karnataka. It is more or less in line with interim verdict only.
Infact karnataka get more share than TN. Understand the reality..
