There are different degrees of sensitivity though. Infrastructure, eg what Coinbase published, are pretty vague in the real terms. A hacker would still need to approach their target in the same way even with knowing this information. But exploits like Heartbleed could leak information about what users are in /etc/passwd, which is a lot more sensitive since that would significantly reduce the entropy needed for a brute force attack against the host.
