Sharing is caring, being forced to share does not foster care.
Companies don't care, so if you release something as open source that's relevant to them, "companies will simply take it, modify it, and never release their changes,and charge for it too" - but that is what companies do, that is their very nature, and you knew that when you first opened the source.
You also knew that when you picked a license, and it's a major reason for the particular choice you made. Want to force companies to share? Pick GPL.
If you decide to yoke a dragon, and it instead snatches your shiny lure and flies away to its cave, you don't get to complain that the dragon isn't playing nice and doesn't want to become your beast of burden. If you picked MIT as your license, that's on you.
