[website] Create case studies

I know I'm breaking every issue rule, so feel free to instant close it. I just dont know how else to reach out to any of the project maintainers (I also know this exact question would get slaughtered on StackOverflow, and I don't want to trash my rep there either....)

We're having a massive debate at my company about weather we want to use MUI... I'm (and most/some engineers) are pro using it, and our UX team wants to build bespoke. We're at a bit of a stale mate... as part of my research, I'm visiting the websites of some of the big players to see what their implementations looks like (or whats publicly visible)

TL;DR;
Is the above list still active users of MUI? And to what extent? Or how would I be able to gather some of that info, if at all?
For example I can see Bethesda has some of the standard MUI classes but with extended naming conventions... but Netflix, my guess is, if they do still use MUI, it's seems to be either modified heavily, or purely used internally?

Start with the linked Trello benchmark and the organizations shown in the issue’s screenshot. Verify whether each listed company still uses MUI and to what extent, then define and document the case studies with supporting evidence; the issue is complete when the requested case-study material exists and its scope is agreed.
