This seems like they are acknowledging the addictive potential of certain web services and are using it to force compliance among their students. I think that is despicable, if that is what is going on.
PS: I'm fully vaccinated. Sadly it seems necessary to make such a disclaimer, lest the hatemob will destroy you and not even consider your argument.
edit: Always interesting to have a controversial comment. I counted -11 +9 so far. I'm seeing very little engagement for that. I don't think my comment was particularly inflammatory, merely poking a little fun at the authoritarian political plays we've seen during this pandemic. So I'm wondering why people are so motivated to vote on my post.
