This seems unlikely. It's not the norm today for closed-source software. Why would it be different tomorrow?
Because we now have LLMs that can read the code for us.
I'm feeling this already.
Just the other day I was messing around with Fly's new Sprites.dev system and I found myself confused as to how one of the "sprite" CLI features worked.
So I went to clone the git repo and have Claude Code figure out the answer... and was surprised to find that the "sprite" CLI tool itself (unlike Fly's flycli tool, which I answer questions about like this pretty often) wasn't open source!
That was a genuine blocker for me because it prevented me from answering my question.
It reminded me that the most frustrating thing about using macOS these days is that so much of it is closed source.
I'd love to have Claude write me proper documentation for the sandbox-exec command for example, but that thing is pretty much a black hole.
I'm not convinced that lowering the barrier to entry to software changes will result in this kind of change of norms. The reasons for closed-source commercial software not supporting customisation largely remain the same. Here are the ones that spring to mind:
• Increased upfront software complexity
• Increased maintenance burden (to not break officially supported plugins/customizations)
• Increased support burden
• Possible security/regulatory/liability issues
• The company may want to deliberately block functionality that users want (e.g. data migration, integration with competing services, or removing ads and content recommendations)

It's always been this way. From the user's point of view there has always been value in having access to the source, especially under the terms of a proper Free and Open Source licence.
