The protections are hardware implemented and cannot be forged in software.

Let’s start with this: MongoDB is accurately referred to as source-available software. Many open source proponents, including the Open Source Initiative (OSI) , do not consider software under the SSPL to be open source. We agree with the OSI’s determination that any software under the SSPL cannot be open source.
