> misdirect Ukrainian drones toward NATO airspace (which has happened).

Claims to such effect has been made in public by reputable persons but they are not very credible nor has any supporting evidence been shown in public.

Drones getting lost due to GNSS jamming is happening.

But intentional misdirection towards a target would require GNSS spoofing capabilities over an impractically large area and that the drones would be susceptible to simple spoofing. They have satellite navigation, inertial navigation, terrain following cameras and listen to ground based radio sources like cell towers and are designed to operate in hostile RF environment. Just sending a fake GPS signal (several of them) won't make the drone divert to a specific target or direction.

I'm not buying the misdirection story until more compelling evidence is made public.

I made no claims as to whether misdirection is happening or feasible, only that there are incentives for both sides to do so if it is, while there are no incentives for Russia to take on a much larger enemy while it can barely handle Ukraine, which OP was implying was the obvious explanation.
