OK, what products have gotten worse under Oracle? How do they compare to their competitors? Why don't people leave Oracle if it is so bad? Remember, people can and do move platforms all of the time. A good example is how the cloud took off despite the huge amount of work it takes to move things to the cloud. My main point is saying one of the largest software companies in the world is "bad" or "makes things worse" sa…
I think most people feel like the Sun Microsystems products all got worse after the Oracle purchase. E.g., Solaris, Java. It's prolly gonna be hard to find any specific metrics to show that, though. But I remember everyone thinking that all of the Sun offerings had gotten worse after the acquisition. And OpenSolaris got axed altogether, of course. And Java had a series of security embarrassments.
After the acquisition I could not reach kernel developers the ones that remained and package management fell into the bog of eternal stench. Generic examples would be moving binaries into /tmp and moving an Oracle specific fix into place because they knew not how to do package management. Eventually it became impossible to do package verification. By this point we had moved most customers off Solaris, HP-UX and AIX over to Linux out of cost optimizations and making everything cookie-cutter but I was happy to depart from maintaining Oracle Sun systems.
At another company I worked for we replaced everything acquired by Oracle to forked alternatives. This was less to do with technical reasons and more to do with legal liability risk as Oracle could at any moment force licensing, change license terms, drop free support, etc... So as an example we moved from MySQL to Percona MySQL. We also quickly moved away from Dyn DNS due to concerns from the federal government and our lawyers as Dyn (Oracle, also being a competitor) could monitor DNS traffic and profile our customers.
