"If the projects get a lot of stars, they become part of the global training set that every coding agent is trained against, and the utility of the tooling continues to increase."
OpenClaw currently has 1.8k issues, 400k lines of code, had an RCE exploit discovered just a few days ago, it takes 5 seconds to get a response when I type "openclaw" in my CLI and most of the top skills are malware. I'm pretty sure training on that repository is the equivalent to eating a cyanide pill for a coding model.
I actually agree with your take that custom apps will take over a subset of established software for some users at some point, but I don't think models poisoning themselves with recklessly vibecoded bloatware is how we get there at all.
