I agree that we should not side-track this thread, and I will use the new one for other replies, but I wanted to clear up a few things that ccooke asserted.
1) SRD5 is not created with the intent of damaging Wizards of the Coast or breaking laws. The OGL is part of the reason 3rd edition was so unanimously adopted. It is also highly unlikely that SRD5 will ever become a profitable venture.
2) As mentioned by another poster, it is my understanding that you cannot copyright game rules, so the copyright statement you have quoted is simply referring to the parts of SRD5 that can be subject to copyright. ie. Trade dress, formatting, etc. Paizo has established copyright for their OGL material as well.
3) As with
all OGL content, you are free to use the content under the terms of the OGL. SRD5 content is no different. The SRD5 Compatibility License is optional, and SDR5 is required to provide it as per the OGL's requirements in section 7, "Use of Product Identity" in order for anyone to be allowed to indicate compatibility. OSRIC does something very similar.
You don't need to use the logo, but if you want to use a logo, you have to use the same one that everyone else is using.
