Wtf are you talking about? Alexi Navalny was nearly killed after Putin poisoned him, but he kept speaking out. Then he was jailed and died in prison while still fighting Putin, and his wife has continued his work since then.
And even though it got swept under the rug fairly quickly, a few weeks ago she was able to get postmortem reports done that showed he most likely died in prison from being poisoned again, even though Putin delayed releasing his body after he was already dead bc he was trying to cover up his murder.
