Oracle has a horrible reputation among devs. But I think they bypass devs for purchase decisions and straight up wine and dine and bamboozle the low information execs. When I worked at a megacorp as a dev, I had near zero say in such purchase decisions. I had to work with what I was given. Thankfully I work for a much smaller shop now. Better pay and much better decision autonomy.
So it's likely that, for a specific task, the oracle solution is crap, but oracle has crap for everything so the oracle sales droid can sell a "one throat to choke, one check to write" policy to a company that likely has technology problems but produces a "not technology" product.
Amazon's moving into this space and their crap is even stickier than oracle's...
