When products with digital elements reach the end of their support periods, in order to ensure that vulnerabilities can be handled after the end of the support period, manufacturers should consider releasing the source code of such products with digital elements either to other undertakings which commit to extending the provision of vulnerability handling services or to the public. Where manufacturers release the source code to other undertakings, they should be able to protect the ownership of the product with digital elements and prevent the dissemination of the source code to the public, for example through contractual arrangements.
