That behavior is controlled by the Mouse Model [1] which can be changed with a selection menu in the bottom right of the window, or by right clicking anywhere in the viewport. I generally use Touchpad. While the default behavior is not desirable for you or me, it is based on a sort of standard interface type, so it's desirable for some. It could be possible to start a discussion about changing the default, but I just wanted to mention that this behavior is not set in stone.

Yes, this can be very frustrating to me sometimes too seeing people dismissed this way. There are several issues at play in the forums. Besides the most obvious one of expert blindness from people who have been using FreeCAD as it evolved, you have the problem of people who have the time and ability to help newcomers but not necessarily to fix tough underlying problems. At some point a certain jadedness creeps in and their desire to help can actually be harmful.
Hopefully after some time you'll be willing to give FreeCAD another shot as it is improving rapidly, although the problem space is so big it can seem to happen in spurts.
I appreciate your feedback on this--I did end up finding the Mouse Model documentation after a bit, but I think there was some frustration built in on my end by that point.
I'm certainly open to trying it again in the future, and honestly do hope that it becomes a feasible alternative at some point. In fact, I think think that for certain tasks, it's not that far away, but I think that some of the UI decisions, whether from expert blindness as you've pointed out or other reasons, will keep coming up as a point of friction for even moderately experienced CAD users from other programs unless there's a deliberate decision made to try to make the defaults and jump-right-in process more familiar to those coming from the existing options.
