I don't really consider it hypocrisy, as I think the primary thing that is motivating them to move towards player safety in the first place is the avoidance of more lawsuits, negative publicity, and other things that affect their bottom line. The motivations are always financially based, and Goodell works for the owners.
On the public face, they can justify it if they expand the rosters, widen the field, and do other things that are a gesture towards limiting injury. (And, no surprise, trend towards making the product more exciting and offense-based.) And the player's union will eventually accept it as long as their slice of the pie is big enough.
That may sound like an overly cynical take. I'm not even sure it's that bad. Injuries probably will prove to be diminished over time. The only way fully stand against them is to say you're against people playing violent games for profit. Full stop. Otherwise, it's just how much are you willing to accept in order to get whatever you get out of it.
