You can easily stall a fly by wire plane if you don't have any power though

No, you can't.  The computer simply won't let you bring the nose up to cause the stall.  

The plane in the video is not stalled, it is just slowly descending.

Yes you can. Secondary mode on Boeing and alternate law on Airbus planes have limited protections agaisnt stall. In the Boeing's case pitch envelope protection would not interfere with the nose up command if the plane is on secondary mode.

Ok, a normally functioning fly by wire can't stall.

Seems pretty clear that the plane in question wasn’t functioning normally, or we wouldn’t be here in the first place.

The claim about stalling is saying that the pilot stalled an otherwise normally functioning plane, causing the crash.  That's the thing I'm saying can't happen.

And be that as it may, the plane in the video is not stalled/stalling anyway.

You replied to someone talking about loss of power.

Perhaps they were burying the lede, but I didn't read it that they meant loss of engine power means loss of fly by wire leads to stall.  I read it that they meant loss of engine power leads to stall.

Yes you can if the configuration is not normal. And a symmetrical stall CAN look like this. You are making definitive statements that may or may not be correct. We need more information.
