But I agree with the other person; if people really won't read any further from the homepage, then I highly doubt they'd read any further than the headline and maybe abstract of the original paper anyway, so there ain't really much upside to linking directly to the paper - whereas there's quite a bit of downside for anyone who might feel inclined to watch the video instead (which essentially covers the same information as the paper, just at a higher level / without the same level of detail) or review the benchmark code - neither of which are accessible from the paper.
IMO you guys (as well as whoever did that) are underestimating the difference in how the two different kinds of submission affect resulting discussion. I did offer to change the top URL to point to the video, if they felt that was more important, but never heard back.
Even that aside, if the authors care so much about what people see first that they actively set a particular URL to redirect to their preference (EDIT: and have explicitly stated that preference in these comments, assuming "apavlo" is Andy Pavlo: https://news.ycombinator.com/item?id=29939332), should that preference not be respected?
