I have never seen a Unity TOS that specified versions as seen in the screenshot of the link you shared. Where did they get that screenshot from? They need to share their source. For all we know this is a change from 2020 (latest version referred to in their screenshot).
In which case I think you will agree that is plenty of notice and most likely unrelated to be maliciously related to what's being announced now. They've even walked back the applicability to old versions as seen in GP.
