Providers of very large online platforms and of very large online search engines should deploy the necessary means to diligently mitigate the systemic risks identified in the risk assessments, in observance of fundamental rights. Any measures adopted should respect the due diligence requirements of this Regulation and be reasonable and effective in mitigating the specific systemic risks identified. They should be proportionate in light of the economic capacity of the provider of the very large online platform or of the very large online search engine and the need to avoid unnecessary restrictions on the use of their service, taking due account of potential negative effects on those fundamental rights. Those providers should give particular consideration to the impact on freedom of expression.
