This is an important point. Also this list by it’s very nature favors schools with less overall majors and more majors of a technical nature. Not sure how useful this data really is considering the number of variables.

That's true, but if your model of using the list is "someone is looking for advice on how to make money by going to college", it is a desirable feature. This person doesn't know what they want to do, and funneling them to a school with only good options will guard them against choosing a bad major later, when they've stopped looking at the list. Adjusting ROI to major availability would make the list less accurate.
Is it? One of my professors kept a table, for a few decades, of his students’ “intended major”, “actual major”, and “job”, and found essentially no correlation among any of these. I’m certainly not doing anything for work that one might guess from my major or minor/concentration.
True - at the same time its easier to switch majors at a school than to switch schools for a given major. So there’s a slightly different risk profile if one decides by major primarily.
