Is there a list of websites that have already shut down or are about to, directly due to Flash Player discontinuing at the end of the year?

No sympathy from me. The discontinuation of Flash was announced 5 years ago. If a web site wanted to continue to run, they have had ample time to redo it. If they didn’t then they must not care.

@elbanditoroso I’m honestly interested to see how it will work out. What other websites and stuff people will be going to and stuff like that.

No

Websites like Newgrounds have found a way to keep their content alive without Flash. We should worry about really old games. Nobody cares enough to preserve them.

No, they have all found a workaround
