Then the only your valid alternative to that is that you are no longer allowed to license code that is unable to be open sourced at the provider level. What are companies going to do, stop making software because they don’t want to open source it? Like there isn’t much a company you can do if they just unilaterally decide that this type of Licensing is no longer legal, companies aren’t going to just choose to not exist because of it they’re still going to exist and they’re not going to shut down over the inability to have a closed Source license after abandonment

The worst case scenario is closed Source license libraries might decide to close because they don’t need to exist anymore which means that companies would be forced to actually design the software they’re working on, but in reality these types of libraries would likely just switch over to an open source support funded tier where they will provide the library is however they’re not going to give any support unless they’re on that subscription tier like how msps are
