Arc System Works gains more autonomy over the game's publishing duties, but it shouldn't impact you in any noticable way.
Arc System Works just announced that the publishing rights for Guilty Gear Strive will be transferred from Bandai Namco to Arc System Works. This applies to the EMEA and Asia regions.
This means that ASW will have full autonomy over sales, promotion, and operational activities for Strive in the affected regions.
This should have no actual impact for players, so you don't have to worry about losing access to anything. However, those who want to contact customer support will need to do it through appropriate channels.
