"If you've worked for us for 24 months and we fire you, we'll pay you for 29 months and give you your next equity and pay for your insurance for 6 months" and "if we fire you we'll pay you an extra ~21% (plus your next equity and another month of insurance too) of whatever you earned" does indeed sound quite nice considering that a vast majority people who are terminated get nothing or next to nothing.

It'd be looking a gift horse in the mouth to whine about "well they get 22+% at XYZ"
