Hi

Oracle recently launched a line of Oracle Certification branded merchandise so that you can display your Oracle credentials with pride. You are proud of your accomplishments and you should be. Show them off.
Based on an earlier survey, we have developed a line of Oracle Certification products to fit a variety of needs and budgets. Wear or carry your credentials with pride. Advertise your hard work and dedication to excellence at the office, at the gym, or anywhere in between with Oracle Certification branded shirts, journals and gym bags.
Oracle Certified individuals will access the store through CertView. The access code provided in CertView is required to enter the site.
Visit CertView now and begin advertising your accomplishments today!
Oracle is a robber baron. You need to pay T-Shirts and other stuff. I would prefer if they bundle a T-Shirt with certificate for free.
Because it's an ad for Oracle brand.
So I understand why Open Source scene don't wish to use Oracle code (even released under GPL or other free license). It's all about $$
