I definitely don't think it's best to start considering legal action against
Fedora users in a thread about invading on user privacy. This will only scare
I think it is reasonable to discuss mitigations to attacks on the proposed
system for counting unique users before implementation starts as that might
affect the design. The new system greatly reduces the cost for pretending to
be unique systems and someone mad at Fedora or just for laughs, might try to
spoof a very large number of systems. Legal risk is one thing that might
encourage people not to do this (possibly to the point where no one tries to
do an attack spoofing say multiple unique machines per second). Another
mitigation is proactively looking for lots of unique machines on a small
number of IP addresses and flagging this for evaluation by a human.
