If I recall correctly, Clint has addressed this on Twitter as well and said that the current issues are:
1 - defensive holding more-or-less fell out of the game due to extensive changes in how WRs and DBs interacted this year, along with adding the new WR - DB user controls, and that building defensive holding back into that new system wasn't priority due to widespread player complaints
2 - the current game styles settings don't support locking / unlocking specific animations and behaviors, only changing tuning values with existing behaviors which are always on
It's not "marketing BS". There are actual technical and project management reasons why things do and don't happen. The sooner we all understand that and show some patience and appreciation for how open Madden is with their development process - especially relative to other AAA video games - the happier we will all be.
