The division of the company I worked for did license it back then in 2011.
Here was the core reason(s)
1) We needed to remove a layer of "communication"
A C-level or SVP needed a report -> they contacted IT -> IT-Dept booked the Business Analyst (a guy who could speak more eloquently about the business but knew some of the components like DB to solve the report) -> Analyst met the C-Level or SVP, mocked up a report on paper -> sent this specification to a Report Writer etc... sometimes a DBA got involved or even worse.. and the cycle continued..
WindWard allowed us cut the involvement down to 1 or 2 people max. Analyst build the report in a workshop in front of the C-level's eyes thus getting it done almost in real-time. That 6-7$ at that time was nothing in the salary costs and angry C-levels.
2) Point 2 - Our reports at the time were primarily "Word Documents" with content and this worked better than anything else to make a Quick .dot (Word template with Winward plugins)
Now in 2016 I think it would be a different RFP/Assessment and someone else may win
Now my 2 cents here with AIM and Word/PDF -
Its 2016 over a decade from the day the source was written for Jasper; included here we started fiddling in 2008 and now re-started a project with it in 2016 (with help from Kingsley and Mark B) we have been able to do alot with the report writer included. Yes it has its moments but strangely is extremely nice.
About replacement:
Yes, we also are looking for a replacement with a Drag and Drop "no code" type functionality and would internally code the integration between AIM and that product in a moments notice once we see it matches the current Report generator.
