(AINAL) No I don't think you're correct, which is what I (and others) were trying to explain. Which is also why MIT and Harvard (and many other universities) sued ICE. Here, copy paste from another comment:
> 19. Plaintiffs have standing to bring this case. Defendants’ actions will cause an imminent, concrete, and irreparable risk to Plaintiffs’ ability to achieve their educational missions unless halted by this Court.
> 20.Plaintiffs also have standing to assert claims on behalf of their F-1 visa-holding students, who face the imminent, concrete, and irreparable risk of harm to themselves, their families, their educations, their short-term and long-term health, and their future education and employment prospects if Defendants’ actions are not halted by this Court.

What you're missing is universities are making their classes online not because they're offering online education, but because they're forced to do so in order to protect students and faculty (including F1 students) from a pandemic. F1 visa specifically gives students right to protect themselves from such risks.
If universities switched to remote education e.g. to cut cost or to experiment with online education methods, then you'd be right. But the argument here is that universities do this because students and faculty face irreparable damage or death, and therefore there is no basis to deport to F1 students.
