At least for the OVH case there is a bit of info:

"This botnet with 145607 cameras/dvr (1-30Mbps per IP) is able to send

Just watch any more or less recent CSI / crime TV show.

They have "an IP", enter it into some gizmo, and it spits out the 
address, mostly shown on a nice sat image.

That is so "normal" in TV that for Bully Policeman it just has to exist, 
and the reaction to a webform where you can enter an IP and get an 
address will just be "great, now I also have this" - no further 
thinking to be expected.

And finding a Judge signing off nearly any warrant put in front of them 
is also not new.

Will everyone use VPN? For sure not.

But everyone that really wants to access something that he "should not" 
by local definition.

Like the kids in the neighbourhood - the firsts parents gets an invoice 
("Abmahnung" in German) for an illegal download of something done by 
the kid, and watch how fast it goes around all of them that you can 
avoid such costs (and more important the trouble with the parents) by 
just installing this "app".

Technical details do not matter, a big enough incentive to do 
something about it matters.

I think you are wrong here for a lot of szenarios.

Today we have for example small web-agency gets /25 from datacenter 
hoster (LIR), puts two servers there, couple of VM, and then rents those 
VM to its 50 customers.
