You should try actually reading BuzzFeed before making blanket statements like that. BuzzFeed certainly does do a lot of listicles, but that's only a portion of the content they put out. If you want to talk original content, just take a look at the large list of shows they have, such as Tasty, Try Guys, Unsolved, Worth It, etc. And that's not even considering BuzzFeed News, which seems to be putting out some of the best journalism of all the domestic outfits recently.
Even the "content repackaging" is still work. What you're deriding here is a form of curation. Personally, I quite enjoy their roundups of the latest funny stuff from Twitter and Tumblr. And some of these listicles are in fact original content rather than merely "repackaged" content.
If you don't like the fluff "repackaged content", that's perfectly fine. Don't read it. But don't mistake the existence of this for a lack of original content. BuzzFeed puts out that "repackaged content" because it's popular and drives eyeballs for advertising. If that's what they have to do to fund BuzzFeed News, I say more power to them.
