In contrast, abandoned open source software can be picked up and updated by whomever gets paid to, where abandoned closed source software needs to be reimplemented from scratch at great expense to the tax payer.

Not only that, open source software can be adopted by the community (who already paid for the development through their taxes) for their own purposes. Consider for example the productivity impact on business that starts using tools that it cannot afford to develop itself.

Office things like document management, workflow management, accounting, but also tools used in the science community, transport and logistics, anything that government does is represented in some other way in society.

This is a big deal and I hope that it will reverberate across the globe and become the new normal.

Whilst we're at it, consider the impact of open data, where government datasets are available to the community.
