Hardware designs and documentation are crucial for the lliberation of hardware. You wont be regarded well by the community if you hide these.
Even if you a proprietary software to design (loss of YOUR personal freedoms) save all results in a format usable in a libre client (OUR freedom is at stake at that point)
