Thanks for your feedback.
For completeness, here's the original EOL announcement from 2017:

It also links to the roadmaps of the major western browser developers, all of whom are ending support for browser plug-ins as a general class of software in tandem with the retirement of Flash Player.

Finally, there are projects around that might be useful for keeping some of that educational content alive. As an example, Ruffle.js is an active project that's attempting to keep a large swath of Flash content alive using patent-free technology and native browser functionality (i.e. plug-ins no longer required). You might point those content providers to Ruffle.js to see if they'd be open to exploring it as a solution.
Alternatively, you could talk to other educators and find or develop alternative content that satisfies your lesson plans.
Good luck!
