Change happens when the necessary force is applied. Sometimes this takes the form of violence, other times of pressure of some other lever of whatever system is in place, in any case it requires people investing in it. Now, the notion of people “fighting for what’s right” is romantic at best. People invest (read: act, put in time / opportunity-cost, resources, take risks, etc.) with the same rationales of any investment: is it worth to them specifically in terms of costs/risks/success-likelihood/payoff? When it comes to these things, the answer is just "no" for too many so that the critical mass required is not reached. We are at a point when most people in first world countries are just either comfortable enough or think have too much too lose (or both) that it takes stuff seriously threatening their way of life at scale to trigger any reaction with a relevant chance of real impact. As long as the bad stuff is either very-bad-just-for-some or not-bad-enough, basically we’ll see people (and lobbies, and companies, etc.) get away with anything.
