Narrow viewpoint
My small company produced a specialized course for law enforcement using Flash back in 2012. It's still in regular use and it's an essential part of our business. It took hundreds of hours of work to create the original course, and unfortunately today we don't have the resources to re-create the course in another format any time soon. So in an attempt to satisfy the fanatical zeal of the Flash haters by killing every possible way to run Flash, Adobe has just done a drive-by sideswipe of our business that will be hard to repair. Thanks a lot! I understand the reasons for gradually getting rid of Flash, but there was no good reason for this hard cut-off that unnecessarily cripples legitimate uses that have no security risk. I think most of the zealots have a mental picture of Flash as being used only on web pages for simple graphical animations, and think it should be "easy" to switch to an alternative format. That's too narrow a view of a tool that was used so extensively for so long.
