I generally opt out of any kind of thing that is going to popup on my screen unannounced. I think there is a grey area on whether those sorts of notifications you mention should be enabled by default. There is an argument to be made that they should be enabled by default, as it's basically a mechanism to train/educate the user that the feature exists. As long as they can easily opt-out. But I do think it's a very different thing between those and what Epic is doing with advertisements regarding completely unrelated games that they want me to play/buy. It serves me no functional purpose, it only serves Epic, especially because the only reason I have Epic Launcher on my system is because it's the only way to play Metro Exodus right now; it's a means to an end.
