I remember a time when skype was p2p and it was easy to find IPs with netstat
ICQ, IRC, MSN, AOL… They all had this problem long enough ago
Someone getting your IP is as big of a deal as someone getting your username.
FTA:
The attack could pose a serious risk to activists, political dissidents, journalists, those targeted by cybercriminals, and many more people. At minimum, an IP address can show what area of a city someone is in. An IP address can be even more revealing in a less densely populated area, because there are fewer people who could be associated with it.
Just because your privacy isn’t valuable doesn’t mean everyone else’s isn’t.
An IP isn’t private. It is literally your network’s public ID. If you want to hide it you use a proxy, not relying on big brother corporations.
Also, sharing your IP is somehow okay if it is with Microsoft who absolutely sell your info to data hoarders and advertisement companies, but not whoever you’re chatting with? If anything, using p2p is more private because then you ONLY share the IP with the recipient.
