Arguably, the best thing to do to "fix" the issue is to be an evil hacker, and do bad things with it, causing damage, stealing people's money, causing Microsoft to be liable, which causes them to get sued, so then they're monetarily incentivized to actually fix the problem. Just, uh, donate the money that was stolen to a charity and not be evil about it.

Someone already is "being an evil hacker" i.e. running ghrc.io

Is microsoft liable for people typoing a "docker login" command? Is there any chance of a lawsuit?

The fact that there is already someone exploiting it, and it's a big "meh" kinda proves the point perfectly that it's not really a big enough of a deal for the world to fall into chaos.
