I think you are taking an excessive interpretation of what was suggested.
Let's level-set on the issue: Of late, GH has suffered a continuous stream of noteworthy outages. It is hypothesized the underlying cause of the instability has been the dramatic rise in submissions from coding agents ("AI"). The open question is how (or whether) GH can get load at a manageable level, with the proposal being, 'don't immediately allocate build/compute resources against any and all submissions.'
I don't see why that is equivalent to rampant disenfranchisement in the open source community. I believe what people have in mind is closer to, "don't immediately trigger an expensive build process as soon as someone submits a pull request."
