You have a point - cheap drones have changed warfare - but you might be simplifying the issue. As some warfare experts online have discussed, it isn't that cheap drones are the only weapon that is used in Ukraine (or warfare in general), it is one option in vast array of options based on the situation (although, agreed, it is taking on a much bigger significance). Look at the war in Iran. They did a pretty standard playbook and use stealth jets and cruise missiles to surgically take out air defenses in order to gain air dominance. This would be very difficult with just cheap drones.
... but, do agree that cheap weapons are still becoming extremely important. Iran is terrorizing the middle east and strait of hormuz with cheap drones, so they are definitely important. Yeah, in the war of attrition, low cost, high-volume options are clearly very important.
It's fairly important to distinguish what kind of drones are we talking about [1]. Iran's using Group 3 drones.
The GP is confusing Iran's neighbours not being ready to counter group 3 drones with the drones being inevitably effective. These drones are by necessity large and slow, because they need a lot of energy and aerodynamic efficiency to get their range. That means that they are vulnerable to cheap counters, which Ukraine is demonstrating very convincingly: even though Russia is now launching 800+-drone raids, the vast majority is shot down.
Even when those drones do get through, they are extremely inefficient. It's not just that they can't carry a heavy or sophisticated payload (more complex warheads are more effective, but way more expensive), the extremely high attrition ratio forces the enemy to try to target way too many drones per aimpoint. Instead of serving a few hundred aimpoints, the 800-strong raid is forced to concentrate on just a few, otherwise most aimpoints will get no hits whatsoever.
But also the only reason 800-strong raids can even be launched is Ukraine lacking the capability to interdict the launches. 800 group 3 drones have an enormous logistics and manufacturing tail, which a Western force would have no problem destroying way before the raid can be launched. For example, Iran in its current state can't launch such raids. So in practice Iran's neighbours would need to intercept only a handful of drones, which is hardly an insurmountable challenge.

How resistant are these drones to electronic countermeasures ?
GPS denial is a mixed bag. After about two years of efforts and counter-efforts, the Russians seemingly managed to build GPS receivers that are pretty resistant to jamming.

It's a big challenge when you run out of interceptors...
We're absolutely not running out of APKWS. They are manufactured by tens of thousands, and Hydra 70s are even more numerous.
