The recent transition of Elasticsearch and Kibana from the OSS Apache license to a dual Elastic and SSPL license could have significant implications for businesses relying on these tools, as it alters the legal protections associated with open-source software. This change, effective from Elasticsearch version 7.11, has sparked concern because the SSPL license requires businesses using ELK functionality to potentially disclose their source code, impacting intellectual property rights and competitive advantage. The move away from the widely embraced open-source Apache 2.0 license has been perceived as a shift towards a more commercial approach, leading to dissatisfaction among users who relied on the legal freedoms previously offered. Many businesses are now considering alternatives, such as Coralogix, which offers similar functionalities without the licensing constraints, as they navigate the legal and operational uncertainties introduced by Elastic's licensing decision.
