This list is pretty interesting. If you don't mind me asking, what do you work on that you requires such sophisticated stuff?

Also, does this work only for browsers or also for mobile apps? I have always assumed that it is always theoretically possible to get data from browsers (very extreme resort is save the browser page / (screenshot + computer vision)); but it can be impossible to get data from apps (especially ios). Are my assumptions correct?

Also can you explain mobile IPs more? If they are such a big vulnerability, why is there no potential solution to them?

Mobile IPs will be a problem until the entire Internet is IPv6. The issue is that there are not enough IPv4 addresses for everyone to get their own IP every time their phone connects to the Internet. So the mobile networks use one IP for many handsets. Block the IP, block dozens of different (innocent) people.

Once we're all on IPv6 we can go back to blocking IPs. But then IPv6 creates its own problems.

Doesn't the same idea apply for normal IPs (non-mobile IPs)? Our computers also don't get their separate IPv4 address. We use NATs. So how can someone block our computer specifically without blocking dozens of innocent people using the same public IPv4 address?

Basically what's different about mobile and laptop IPs?

CGNAT is done at a ridiculously large scale in mobile networks.

Your home or local coffee shop might have 10-20 users max behind a single IP. A mobile network on the other hand might put most a small-medium city behind 3 or 4 IPs.
