I suspect what we might actually see in that regard is something similar to Minecraft (the Java based one): people were regularly modding it because it was Java based and easy to decomp and know where to inject a mod.

So the Minecraft crew would regularly release updates and obfuscate the code again - most updates were to fix issues/add features, but some were purely for obfuscation. So if you wanted your mod to work it meant not playing any other version.

I'm guessing we'll start seeing more regular updates from software makers; will the updates be fixing bugs or adding features - sure - but I'm guessing that quite a few updates will be simply to obfuscate the code and change addresses around so that any mods that worked before, won't in the new version. Sure an LLM could just decomp it again, but I figure most people won't want to spend the tokens/time it takes for the LLM to actually do the work on that new decomp effort. And with the fact that most people have "auto-update" defaulted to on, I'm foreseeing that apps will get auto-updated likely daily in the near future to combat this.

Years ago, someone once told me "I hope you live in interesting times" ... I don't think this is what they had in mind.

This already happens and has been happening for a while, especially in the Apple ecosystem. I can’t even count the number of apps that did something novel, got popular, had that novelty restricted by some update, then got “replaced” by an Apple app/feature as though they never existed.
