I love open source, but you are correct in identifying it as a very similar problem, though it's more a problem with software licensing than source code being publically available. Usually the argument is made that FOSS ends up as free labor, which is true in a lot of ways, but I see FOSS devaluing software as a whole. When software is open and libre, that sends a psychological signal that the software isn't that valuable. There would still be FOSS in a world where even projects like React charged a licensing fee to big organizations, but in that case there would be more choice between YOLO with free software or paying for quality software; as token expenses have proven, many companies could absolutely pay for the latter many times over. In terms of specifically open source, however, companies get a bit of a loophole in that their own employees (or LLM of choice) can be "inspired* by the source code and clone aspects of commercial software. This has the effect of devaluing the skill of individual software engineers to being glorified script kiddies.
