What Musk did say is, "Tesla will not initiate patent lawsuits against anyone who, in good faith, wants to use our technology."
Furthermore he said, "We believe that applying the open source philosophy to our patents will strengthen rather than diminish Tesla’s position in this regard."
And given that this was posted 3.5 years ago, how about "announced" rather than "announces"?
