That's a strange read on Reddit. I've heard people say this before, and it's baffling.
Reddit is, and always has been, a link aggregator first and foremost. Of course it's reposts and screenshots of others sites. That's kind of the point. To bring you Twitter so you don't have to actually be on twitter.
PS for those unaware:
If you use Firefox, you can add a custom Search engine with the Search URL string:
https://www.google.com/search?udm=14&q=%25s
Then set that new custom Search engine as default.
