Very classy post. To-the-point. There are limitations with digital services.
If you don't like what happened, you need to change things. They only way to change things is to change the law. This begins with voting.
Modern labor rights, environmental policy, and basic equality for marginalized groups (women, POC, LGBT people etc.) under the law, are frequently touted as victories of liberal democratic systems but almost all of these rights exist because of massive civil disobedience, and often violent protests.
In all cases, you need huge support of the voter base for a particular issue before voting for a candidate to represent it is ever an option. Even then, there is simply no way to hold elected officials accountable to implementing their platform, and how could there be? No plurality of elected officials would ever want to pass that law in the first place.
You do, typically, need a majority of the voters to agree with you. In representative democracy that means you need a plurality of representatives.
Candidates can and do lie. That is something you need to evaluate as part of voting for them.
Anonymity doesn't exists for GAFA or Big governments on internet that's all, if you are not happy with that, you can vote as you want it will not change. But anonymity in society will soon stop existing as well. With all cameras that we have everywhere, we just need the Chinese facial recognition system and that will be the end. That's how it is.
- Same point as before but indirectly: gather public support by leveraging the (social) media available to you.
- If all else fails: run for office yourself.
I advise all, especially Americans, to do this first.
