I do think it would be cool for them to keep offering downloads of the installer. Adobe should be proud of shockwave and show that pride by keeping the installer out there.
But how can you be sure these are legitimate copies of Shockwave and/or Flash?
But, many people do you think are going to go and check the hash beforehand? How many people even know how to check the hash? Admittedly, the type of user who will go through so much effort to run old Flash content probably skews more technical, but the point remains.
The alternative is that Adobe could just leave the downloads links up under a giant "Not Supported Don't Use" banner. I know which option I'd find more responsible.
Confusing, yes, as Flash was sometimes labeled as Shockwave Flash.
In addition, everything I said applies to Shockwave as well, albeit to a lesser extent.
(Also, what the heck is with that confusing name? It made troubleshooting a Shockwave issue quite annoying a couple years back, because all my searches for "Shockwave" turned up results related to "Shockwave Flash".)

Scroll down a little further. There's a subhead titled "Adobe Flash marked for retirement as well"
Yes, using unmaintained software is bad for security. However, the alternative of forcing people to use third party sources—which will all be somewhat shady, since Flash is technically under copyright—is even worse for security! Now, you might be downloading a fake, malicious copy of Adobe Flash! God knows there are enough of those already in circulation...
Put it up on a public company archive server somewhere. I really like what Panic does, all software vendors should have something similar: https://download.panic.com
