With growing tensions between the US and EU, European enterprise customers' concerns about data privacy are growing.

In order to continue using Firebase as a core technology stack, customers are demanding additional assurances, such as CMEK or even externally managed encryption keys (like those managed by Thales or T-Systems).

Often, those enterprise customers are major revenue drivers, making service providers dependent on Firebase question their choice of Firebase as their infrastructure.

This can be a primary driver for adoption away from Firebase services as a whole to different services or platforms.
