EAM is actually significantly more popular than EIS, so it might be more accurate to compare EIS to New Coke, and EAM to Coca-Cola Classic.
Obviously there are going to be those (such as yourselves) who are not happy with the announcement. That's always the case when there are major changes to product lines. Once we get the code for EIS pulled from the codebase that EAM is built from, and everyone gets settled in with a new solution for managing network connections (either a Windows Firewall manager or another third-party firewall), hopefully everyone will see the improvements to EAM and feel that this change really was for the better.
That's why we decided to give everyone a 50% extension to their EIS license keys once the automatic conversion to EAM happens. We hope that while some will be sad to see EIS go, that everyone will still feel like they were given a fair deal.
You're right, we did expect that. No matter how good or bad a decision may be, there is always a certain amount of backlash from those effected by the decision. Hopefully in the coming months we will have the opportunity to show everyone that it was the right decision.
