Yea, this shouldn't be surprising at all. Every company I've ever worked had some wiggle room with salary and equity, but when it came to the legal terms, they were not negotiable. I tried the cute "redlining" thing a few times, and without exception it always ended up with a stern letter from Legal: "Sign it unmodified or GTFO!"

I don't know who all these Captains Of Industry are who claim to be able to actually negotiate any of these terms with their company's legal department. Unless you are some kind of unicorn super-star or exec, I don't see any company wanting to deal with the hassle of negotiating a special snowflake contract for you.
