hi I'm the founder of GreyNoise. Not our intention at all to fearmonger on this. Buying our products doesn't do anything at all to "fix" or "solve" this phenomenon. We still haven't figured out the "why". That said, for better or worse GreyNoise is a venture-backed for-profit company that sells stuff to big corporate clients and our website is pretty geared towards doing that.
The intention of this post was to elicit responses from the community, just like yours. So, thanks for reading and thanks for the feedback.
EDIT: Shameless freemium plug: We give our product away for free at viz.greynoise.io
Yup- we've actually been monetizing it for about two years now. Our customers pay us for 1) significant API usage and 2) commercial rights to the data. The visualizer is really more of a way to get people excited and get their feet wet in the data.
