> I don't like putting the blame on the builders
Like it or not if you knowingly build stuff that is used for evil purposes you are complicit
You can't build an orphan mulching machine and get away with just a shrug. "I don't really agree with mulching orphans but someone else paid me to build that. If I didn't build it someone else would have" just does not absolve you of your involvement in mulching orphans
In reality things are much more mundane. You build a custom blog framework, it can be used for good or bad. You build a better app framework, it can be used for good or bad. There's nothing you can build that will not be used by bad people. Canned food and radar came from war. Depending on which side you were, it was used to do good or to do bad. Technology is just that, technology. People are still under the marketing spell of US companies that invited engineers to "change the world". People assumed in a good way. In reality you just change the world, as the other people see fit.
