I'm not thanking anyone.. I paid a lot of money for the instrument, that's thanks enough.. Back 20 years ago, a number of library and patch companies, tried to insist the same..
You can use the patches as you see fit, you do not have the right to repackage and sell them.. All music and aspects of music are built off something previous.
What if Bach's great, great, great, great grandchildren tries to sue for the rights of one to use 12 tone scales..
What if Con Edison, insisted we thank them on music released using electricity?
If Yamaha wants to pay me to endorse and mention their products, I'd be glad to do that, but I need $$$$..
