In this case it’s more of a switch away from the last cool new thing. Totem (like Music) was built around a media library navigated from within the app. By default Totem doesn’t even support opening videos from the file manager, which is something you would probably expect of a video player. It also crashed for me when I tried using it as intended so I’m not surprised to see it replaced by an app that really is just a video player.
That said many apps get replaced not for feature reasons but just by being GTK3, and they tend to get replaced by their own forks to GTK4 (such as the upcoming replacement of Evince). Why their devs choose to upgrade toolkits this way I cannot say.
How was it an obvious data breach? The attack was done via Codebergs notification system. It’s no different from the notification you got from me writing this comment.
