Re: This is something that needs paying attention
There is a lot of bloat in military hardware admittedly, but it's not as simple as buying a a ton of consumer grade devices to replace the military ones.
Firstly, at the moment one operator can only fly one drone at a time. Yes if it gets shot down they could immediately launch another, but thats not particularly effective since the new drone still needs time to fly to where the old drone was to continue its mission, etc. But there are no actual swarm technologies currently flying. There are plenty of research projects exploring this, but there is no actual current way to fly multiple drones in a swarm in a military environment in a useful manner (the drone "firework display" type of swarm is not useful in the slightest in a military application).
Secondly, as has been found in Ukraine, tracking of civilian drone signals back to their operators is relatively easy. This means in Ukraine most of the time, the drones are flown very fast, on a recon mission, and then the operators haul ass to avoid retaliatory artillery fire. Military drones have encrypted and hardened comms to prevent this. In addition, the technologies exist now to disable civilian drones (jamming) at considerable distances. This so far hasnt been used in Ukraine, primarily because neither side seems to have this technology in place (surprisingly), however, the technology exists and is already in place in various airports and protecting military installations in the west. I am surprised this hasnt been implemented at least partially yet, but maybe both sides like having the recon ability? Again military drones are hardened against this sort of jamming technology.
Thirdly, civilian drones are only particularly effective at recon. They cant carry a heavy enough payload to carry a weapon that can deal a great deal of damage (in a military context), perhaps a single grenade, whereas military drones are usually much larger and designed to carry much larger weapons, up to and including multiple missiles. Just ask Afghanistan how effective those missiles can be at destroying things.
And on the recon side, a civilian drone usually has just a single camera. Military drones, usually carry various grades of optics (infra red, higher quality optics, etc.), can fly higher and with a greater field of view, and so are much more effective at observing without being seen.
The civilian drones have done wonders for Ukraine so far in the war, but as both sides start developing anti drone weaponry and technology, you will see the larger military drones having a much larger effect, as it did in the early days of the war when it was the large Ukrainian military drones, who effectively wiped out tank columns, with well placed missile strikes. That's not something the civilian drones will ever be able to do...
