> everyone who worked there has a black mark on their CV I hope this is hyperbole. Rank and file employees are not responsible for corporate policy or direction, especially in places like Oracle.
It really isn't. Oracle has had a terrible reputation since forever, and every ex-Sun engineer I've met has taken great pains to explain they did not join Oracle voluntarily. It's kind of like working for a tobacco company or arms manufacturer in payroll or something: you're not directly responsible for killing millions of people, but by choosing to work there you're still kind of condoning it.
What about Google, Facebook & Microsoft. They do some things that are disliked by many. Should we consider that the engineers who work there are indirectly condoning the no-privacy, ad-infested dystopia that HN hates, and should they be penalized. I bet many of these companies and a lot of others use Oracle products and there by support them directly with money. If you know that your favorite website/product is built on top of Oracle database/products, will you stop using it?
If Oracle (or any other unpopular company) employees are really shunned, then that's only because rejecting them is a no-risk, no-cost, easy thing to do.
