Almost all serious players are present at major conferences & announce that in their blog/social accounts. Pick {Google, Meta, Microsoft, Snap, Netflix, ...} and they are present in {Neurips, ICML, VLDB, HOTCHIPS, Supercomputing ...} with <N> accepted papers.
How is this presence any different to make it worthy of HN mention?
Are the topics they're presenting "solved", or somehow not interesting? Do you think their presence pushed out more interesting topics?
I'm not sure I comprehend the immediate attack for, what appears to be, some neat research. Especially when that research is in the practical context of a game engine that requires good performance on extremely restricted compute.
I _dont_ have a problem with Roblox. FWIW I never used any of their product. I _dont_ have objection if HN discussed any of their papers published in SIGGRAPH specifically.
I _do_ have an ideological problem about a general blogpost announcing their corporate presence at conference <X> being promoted here on HN. If it was Google or Meta doing the same, my reaction would be 100% the same. Such low effort corporate advertising should not belong here. BTW, Google Meta MSFT all have such posts - and with good judgement (with the company of folks here), HN people don't post them
