If that wasn't enough time to move on, I don't know what to tell you :)
Laughably, they claimed this was ethical to prevent users from accidentally running insecure versions after they stopped patching.
I can still install Basilisk and run HyperCard stacks I wrote 30 years ago, but I can't run the dozens of games I wrote in Flash. It destroyed a good chunk of my life's work.
So your comment is rude. It's fine to move on and work in other languages, as I have, but to not be able to even show 80% of your portfolio because it was intentionally crippled by the company you rented the software from that you used to make it, isn't something you can move on from. It's been disastrous.
It's no different than what happened when the C64 when the way of the dodo
Or folks who built stuff for DOS, and never updated to Windows
Technology moves on
Languages and platforms get deprecated and/or die
And if "80% of your portfolio" is on a now-dead platform, I'd say it speaks more to you not wanting to do something new than that you happened to build a bunch of stuff on something now dead
I get that it sucks that stuff drops out of support/manufacture/etc
But it happens
You can be sour about it, or realize it's the nature of life, and move ahead :)
