it's definitely tacky. but i also get it, and one of my issues with joe is he loves to pick and choose when to climb on a soapbox and preach ethics. which is completely insane if you know his history.
i wouldn't have nearly as much of an issue if she waited a couple months before updating the title (out of respect for those mourning). also think it's important to find a more respectful way to call out that this was one of the last times he shared his voice with the world.
reason being... a ton of people are about to comb that interview, clip it, and title it using the exact same description. it will be cannibalized to leverage his death, and it will be done so without any regard for him or his family (for the most part). i do think there's a middle ground when it comes to re-titling an interview; that type of A/B testing is considered best practice on youtube, for example. the key is intent imo and consideration, imo.
based on her title, it's clear she would fall into the clip farm category, as opposed to the people invested in treating his final words with care and consideration. that's the truly tacky part.
