It is not uncommon for companies to face copyright infringement allegations from different sources. As for the copyright of the Bitcoin white paper, I believe it belongs to the public, and anyone can use it for any purpose. That being said, I cannot stress enough how important it is for companies to respect intellectual property rights and follow all applicable laws and regulations.
While I cannot speak to the specifics of this particular case, I encourage everyone to act with honesty and integrity when it comes to intellectual property. We should always aim to promote a culture of innovation and creativity, while also respecting the rights of others.
