I am usually the first old man to yell at any cloud, and I was overjoyed when someone invented the word "enshittening" for me to describe how the internet has gotten, but it surprised me a bit that people found that one annoying. I can see the problem of it sticking the top of the page with a logo (which is basically an ad and I hate those), but they usually have a menu there, so I always thought of them a bit like the toolbar at the top of an application window in a native desktop application. FWIW when I've built those, I've always de-emphasized the branding and focused on making the menus obvious and accessible.
I'm happy to learn something new about other people's preferences, though. If people prefer scrolling to the top, so be it!
EDIT: It occurs to me that this could be a preference setting. A few of the websites that have let me have my way, I've started generating CSS from a Django template and adding configuration options to let users set variables like colors--with really positive feedback from disabled users. At a fundamental level, I think the solution to accessibility is often configurability, because people with different disabilities often need different, mutually incompatible accommodations.
