I vaguely remember reading a similar Open Source License, but couldn't google it.

And it reads very AGPL like. Which may be a big no no for many Cooperation and Enterprise. And what if the Author Set a Grace Period of 50 years or longer?

It feels to me a solution looking for problem.

It is a solution for people who want to keep their software proprietary because they think they can't make money out of it if it is open source. All the while they get to claim credit for it being "open source".

The problem is that this license completely obliterates the major points of OSS licenses - which are open collaboration and security. Nobody is going to contribute and fix bugs in old versions of the software which may not even work anymore (e.g. because some underlying protocol or infrastructure have changed already).
