That definition may be a little broad without some qualification. Most of the US’s large universities have some kind of online program, and some kind of relationship with the federal government. I went to a private research university that had a large online program and deep ties with the federal government. They had real-world residential campuses, research labs, multiple supercomputing clusters, etc. They wouldn’t have met a diploma mill definition though. The online courses were format adaptations of the in-person courses, and where a lab couldn’t be designed digitally there were IRL requirements. The dropout rate between online and on-campus students was about the same. Faculty were mostly retired or researching and field-practicing PhDs or Masters candidiases (TAs). I did both, and found no real difference in rigor. I have heard it said that regional vs. national accreditation is the “real” red flag.
