I used to work for Oracle. I'm still friends with people who I worked with at Oracle. Many of my current colleagues used to work for Oracle. My current manager, and his manager too, used to work for Oracle.
Did we always agree with the decisions of Oracle executive management? Nope. Of course, so long as you work there, you can't say that publicly. But, even though there's quite a few things that Oracle did while I was there that I strongly disagreed with – I can't see the problem with charging extra for supporting really old versions. It is just common sense, and it is part of the package the customer signed up to at the start – the collateral given to the customer as part of every deal explained it. Many other vendors do it too. A consumer might legitimately claim they didn't understand what they'd signed up to, but that's not believable when a billion dollar company signs a million dollar deal.
Oracle has over 100,000 employees today. I have no idea how many ex-employees there are – I've met so many over the years, we are everywhere – but I guess it must be well over 1 million by now.
You are deliberately putting in extra effort to make your own product less secure. Often with consequences that will primarily be felt by people far down the impact chain, who probably didn't even know that the choice was being made.
That's just a prettier word for the same thing.
And bringing up Oracle as your reference for ethical behaviour is certainly... a take that doesn't really say what you think it says.
