Enterprise customers want the ability to pull their keys and walk away from a platform, sometimes with very little notice.
A made-up example: assuming Brexit occurs, EU customers of a London-based SaaS chat service may no longer wish to keep that data outside of the EU. The easiest way to wipe it out quickly?

Some companies would rather have the option to destroy it and face the consequences, whatever they may be.
