Are studies like this done to justify an actual Vitamin D study? They need to take a sample of confirmed COVID patients and test their Vitamin D levels individually.

This site is filled with introverted engineers -- not exactly a representative sample. 3.4% of kids are homeschooled, 64% of which are doing so in order to provide religious instruction.
I understand the reticence towards third party telemetry, but refusing basic interaction tracking for a product you pay for is just hurting yourself, even if you're already satisfied with the service. You don't go to the doctor for a checkup and then refuse bloodwork. Obviously there are rules around privacy for medical records that don't exist for interaction tracking. But I don't think the solution should be to get rid of tracking entirely, it should be to extend reasonable privacy rights and protections to our online data.
In regards to your points about research, maybe the math department should consider establishing a "teaching professor" role like the EECS department has done. Most of the lower division introductory CS courses are taught by teaching professors like Paul Hilfinger, John Denero, Dan Garcia, and Josh Hug. Given that math is so important to a variety of majors on campus, why shouldn't we demand that large, lower division math courses be taught by people who are experts in teaching?
Also, class time is split about 60/40 between professors and graduate (sometimes undergraduate) student instructors. Class size for the student instructors is 25-30 and class size for the professors is anywhere from 100-1400, depending on the class. Some upper div classes are notably smaller, depending on the department. It's my understanding that this setup is pretty common at large public universities.
