[MIT] doesn't give developers any guarantee

I assure you GPL doesn't either. You can jump up and down furiously waving GPL all you want. Nothing short of a paid legal team would enforce it.

And even the threat of that (and *GPL’s viral nature) makes it INCREDIBLY unlikely legal teams allow employees to even use binaries of the code on their workstations. Of course nothing is actually stopping them, and it would be hard to prove it if they did, but there is at least some semblance of a threat.

MIT and similar are simply roundabout ways to make it public domain.
