Science isn't just about discovering information. Dissemination is critical. Communicating ideas is just as important as discovering them and promotion is part of effective communication. It's natural and healthy for researchers to promote their ideas.
The "marketing" page is where documentation is. Summaries that don't require reading a whole academic papers are a good thing, and they are the place where all the different links are collected. Same reason software has READMEs.
Logos... are cute and take 10-60 minutes? If you spend months on some research might as well take the satisfaction of giving it a cute logo, why not.
Is your position that any write-up about an attack must be plain text only, and must not use its own URL?
I truly cannot understand why this is brought up so often. You aren't paying for it, it doesn't hurt you in any way, it detracts nothing from the findings (in fact, it makes the findings easier to discuss), etc. There is no downside I can think of.
Can you share what the downsides of a picture of a puppy and a $5 domain are? Sorry, "branding" and "marketing page"?
Or at least, maybe you can share what you think would be a more preferable way?
Dunno, but I'm glad they do it. In other fields of research, researchers often purposely hold off on naming something, so that the community kind of has no choice but to name it after the authors themselves.
Eg in my field, they would have called Spectre "the Horn-Genkin-Hamburg vulnerability" or something. Which one of these is hard-to-remember jargon, and which one is catchy and evocative?
Because it makes it feel like you need some marketing department if you want to publish your work.
Rather than give _only_ the work merit, we give too much merit to its colorful presentation.
That shouldn't be the case.
