You don't get that something proprietary was stolen and the creators are upset? From a software perspective you can't imagine how you'd feel if a critical piece of your business software was reversed engineered and copied by a competitor? An example might be finance and low latency trading. Or an ML / AI breakthrough. Or anything on the fringe still providing a competitive advantage and not a solved problem on Github…
Maybe I'm a bit too much of a STEM-headed engineer but I think you are making a false comparison. UX is fleeting. Even the best UX will grow stale over time as styles change, and it's style propagates (as it will if it is truly revolutionary) it will become mundane. Technology breakthroughs are hacks in the laws of physics. Humanity hasn't fundamentally redesigned the Steam Engine since James Watt. It just can't beco…
One analogy is brute force searching for an approximate solution to an optimization problem.
It's problematic when others take your solution if you did all the brute forcing.
Design is only fleeting inasmuch as an approximation could be fleeting. Others build off an approximation to find better solutions. But without the earlier solution, we'd find ourselves in a much different part of the sample space.
