It is not about the drivers, framework has most likely not the capability to develop drivers for their Laptops, it is the manufacturer’s job. All framework can do is selecting parts that are already supported by the kernel. Also a driver can take several years until it actually gets into a not rolling release distro like Ubuntu or mint since they do not use the newest kernel.
This collab is more about making sure, that when you install those distros everything works out of the box which is not a given, depending on the compile flags for the kernel they used or what packages are coming installed by default.
What do you mean with encryption? Does it need to be transport encrypted, end to end encrypted or is encryption at rest (when the server is offline) good enough?
