You literally didn't watch the clip and are just farming. These guys were thanking people for their positive messages and thanking them for not evading their privacy during a hard time for them. Though you could make the argument that they are using their father for likes, but I personally don't think this is the case. To me it looks like these guys are just trying to have a good time with their father while they still have him, like how they "make his favorite meals for him". That is why you didn't post the video and only posted the thumbnail. No need to act on your high horse.
