Stackblitz Webcontainers[0] look promising too. I read the creators plan on open-sourcing the underlying tech once more mature.

Yes for all of us but all corporate clients will flock to github to benefit from those surveillance capabilities.

How about moving all our code off GitHub while we're at it?

In this worst case scenario (which hasn't happened yet), I'm sure GitHub would expect the good will of open source projects and contributors while simultaneously being the boot on their face in the workplace.

I have projects on github because some of my clients requested it. My own projects stay off. Other than renting physical servers I do not use a single piece of software for my own business that forces me to subscribe and be online.

I've been on sourcehut for a while now. It's great.

Unfortunately it's your company that signs up to this sort of thing, not you.
