The COVID-19 pandemic has accelerated the adoption of new technologies and raised societies’ technological development. Legal regulations play an important role in the implementation of the latest technologies. The contact tracking applications that have been deployed almost all over the world do not, in most cases, provide an adequate level of personal data protection. An essential aspect of competition law regarding data protection is ensuring data security (trade secrets, personal information). Although entrepreneurs’ use of cloud data stores is well-established, we have never witnessed adoption on such a large scale as during this pandemic. This was influenced by, among other factors, the need to provide remote access to enterprise resources despite limitations on the movement of people. Furthermore, because many companies faced an immediate need to enable remote working and collaboration, many solutions were adopted without the usual due diligence that should apply to such a business decision. Therefore, questions arise as to whether the legal frameworks for the functioning of such data ecosystems ensure their security. Moreover, since technological innovations are of key importance for sustainable development, it is worth reviewing the framing assumptions (concerning sustainable development) of active sustainability initiatives and the possibilities of still achieving their goals despite the major setback of the pandemic. Furthermore, the rapid and forced changes resulting from the coronavirus pandemic cannot remain in place without adverse impact on the data protection landscape. During the pandemic, legal regulations regarding personal data protection, environmental protection, and competition law began to be questioned. The author shows that the legal regulations in force in these areas are no longer sufficient and require adaptation to the rapidly changing reality.
