Coop (the biggest Danish retail chain with several brands) was just hit with a license claim in excess of 100 million Danish kroner (more than $16 million) by an unnamed vendor – see e.g. http://www.computerworld.dk/art/56271 (in Danish). They are known to be a big Oracle customer, but also have Microsoft software.
In the end, the vendor had to drop the claim and received zero kroner, but an inestimable loss of reputation. The customer is quoted as saying “if there is any way I can change vendor, I will do so”.
Sadly, everyone assumes that Oracle was the culprit. This might be true or false, but it does say something about the reputation Oracle has garnered lately.
