It's more likely we'll see more laser based anti drone systems, more sophisticated EW and more ubiquitous smart AA guns with aided targeting than missiles, since those will probably always be more expensive that the simple drones they're trying to shoot down.

Secondly you need a proper integrated defense network, that can detect targets as quickly as possible and prioritize them between different types of interceptors, you don't want to be shooting patriot missiles at Shaheds, but you might want to do just that for enemy aircraft / ballistic missiles. All of this is extremely expensive and difficult to build.

In Ukraine biggest problem with handling the missile/drone attacks is that they come in waves that generally overwhelm air defense, and even then most of the damage is not done by drones/Shaheds but large cruise/ballistic missiles, which are often even harder to shoot down.

If last couple of years have shown anything, it's that basic utilities (which internet is at this point) should've never been privatized to begin with. So this isn't really about Musk, but about the entire private sector.

6 billion might sound like a lot of money, but this is money & know how that will largely stay Europe, with EU maintaining control over it, instead of relying at whatever bait & switch scheme Musk and the likes come up with.

Not to mention stuff like this also has military/defense purpose, and leaving that in someone else's hands is a bad idea if you want to rely on it.
