* Co-Pilot is trained on copyrighted code without attribution: ludicrous?

This is debatable, but yes, it's a ridiculous reason to not use github. If your code is on the internet, which it is with every other alternative host they mention, it will be crawled and used for training, just as it will be read by humans and learned from. We can have a fair use debate, but GitHub is not alone in this stance or problem set.

* Github works with ICE: incoherent?

No, I would file this under ridiculous. GitHub is a government contractor. It licenses it's software to lots of organizations. People can disagree with a lot of them, but trying to manage that and dictate changing political morality at a company level is insane. All of these other solutions are certainly used by organizations that are a lot more controversial than a major federal institution, as much as I may even personally disagree with policies under certain administrations. But again, singling out GitHub is just finding some reason to be mad, it's not GitHub specific.

* All of Github's hosting code is proprietary and secret: ridiculous?

The computers that you're writing your FOSS code on, that indeed they wrote this article on, have proprietary chips, have software you can't access. You think everyone at SFC uses a Stallman-esque laptop? They're probably happily typing away on their Macbooks, full of non-FOSS software. The software community is an ecosystem of lots of models, nobody is all-FOSS, it's not possible. GitHub has open sourced Electron, libgit2, a thousand other things. Core code was never helpful to anyone and would not be helpful today. Git isn't a lock-in proprietary thing, you can always easily transfer your code elsewhere.

* Github tries to discredit copyleft: hyperbolic?

It doesn't try to discredit copyleft as a corporate stance. Several individuals have pointed out weaknesses in copyleft vs permissive OSS licenses. But it's never that you should use closed instead of copyleft or something, it's always something like if you're using copyleft, it's generally better for the community to use MIT or Apache or something more permissive that doesn't need to involve lawyers and gives you more freedom.

* Github is wholly owned by Microsoft who also doesn't like copyleft: conjecture?

This is a 30 year old take on what Microsoft cares about. Microsoft probably never thinks about copyleft these days, any more than the rest of us do. MS contributes to Linux, contributes to Git, both GPL projects. Almost certainly they contribute more to GPL projects globally than you or I or the SFC do.

> As to SFC not having anything better to do... this is exactly what their mandate says they should do

My point was that they can actually help the Git project by sponsoring meetings, educating people in a useful way, etc. I have helped donate a fair amount to the SFC through GitHub events and was hoping the money would be better spent on actual community building and project fostering rather than cheap think-pieces like this.
