We built a vast surveillance network under the guise of servings ads and making money, and lost track of how this power could be abused by an entity not aligned with our own values.
For example, we all stood by when we let Twitter and other US-based social media become the main way politicians communicate with the public. This has, in my opinion, had disastrous consequences on how they communicate and actively blocks politicians from achieving consensus.
This is to say that you don’t need to have actively worked on something.
However, I think a lot of people in tech could and did see those consequences coming and were pretty vocal about it. So, I don't think we all did stand by, we exercised what limited power we had. I don't want to seem accusatory here and I don't mean it harshly, but maybe you just didn't see the folks who have talked about problems like this.
We also as individuals [without billions] have fairly limited capacity to directly act against these things. I donate a fair bit to the EFF for instance and I've sent outreach to representatives multiple times over the years for specific bills and when its possible I vote against surveillance.
