How have these changes affected the supply chain in these sectors?

The text does not provide specific information on how the regulatory landscape in these sectors has been affected by the changes. However, it can be inferred that the sudden shift to online platforms for healthcare, education, and grocery shopping due to the pandemic may have necessitated new regulations or adjustments to existing ones to ensure the safety, privacy, and rights of consumers.

The implications of these changes for the digital divide could be significant. As healthcare, education, and grocery shopping move online, those without access to reliable internet or digital devices could be left behind. This could exacerbate existing inequalities and create new ones. However, it could also spur efforts to close the digital divide, as the importance of digital access becomes even more apparent.
