I'm guessing you're being deliberately obtuse here. You were completely free to do with your work as you please, and you "pleased" to sell your work to a company in exchange for some consideration. If you don't want IP transfer, or first-refusal fixed price patent transfer, then don't sign that employment contract. I had them negotiated out of my last agreement, and I'm free to spend my personal time creating whatever I want, knowing the rights to it will be owned entirely by me.
When you still find an employer, that makes a contract like that, call yourself lucky. In my country, it is a law -- and you can't cancel out laws in my country in contracts.
Not everybody is so lucky, that he has enough money or finds fitting freelancer work.
Ask the music people. They (oftentimes) can't sell their music without having contracts with big companies -- and they have to sell out all their rights.
But it seems that you just view the world from your standpoint -- fading out any negatives -- and everybody that has different experiences as you do, is just stupid or "obtuse" in your view. With such an attitude on your side, a discussion makes little to no sense.
