Hat: open.*project person.. With the complaints we get often the people aren't properly secured, they are just seeing the noise in their logs or they just started logging.
We often get more complaints after the first six months as someone says "oh hey, we updated our IPS and now see the NTP traffic that we didn't see in 2000-2015, lets complain about it". It's good they have visibility now but most people don't get the true issue or impact, and don't even appreciate it when they are on the receiving end of a 100-250Gb/s attack from these services. Take a moment to read the Christian Rossow paper called "amplification Hell". While amplifiers are only a part of the equation, the trend of fixes is important to track so people understand the state of the fixes.
