>Why are we now conflating business viability with technical or security chops?
Technical ability has helped many startups leapfrog others in a similar space and time. It's the lore which HN is based upon. In a scenario where lots of actors are trying to censor your site, having great tech chops can help with resilience. Technical ability unlocks new revenue streams and optimizes existing ones.
Viability starts to approach zero if the business faces security issues. Its as if the hull of a ship is breached. The safety of everybody on board now is at risk. People literally get murdered when the wrong DMs or photos leak. Exposing your users digital life to grifters and governments a huge risk to them and your business as a result, let alone the hard cost of managing a data breach. Companies recognize these risks and put checks and balances in to ensure that these things get caught. Some even have a fiduciary responsibility to do so. That said, when a CTO decides to push code, they generally have the ability to override any of those safety systems.
I think you're spot-on that extremist companies can't grow very large and struggle for talent.
It's entirely possible to generate lots of wealth while advocating for wealth to be distributed more broadly. One can argue and support reforming how Trusts are taxed, and may make a bigger dent in the problem than they could by holding up a sign on a street corner. I don't see entrepreneurial success as antithetical to progressive causes. Using the position of power that your success affords to change the rules of society to benefit you and yours... that there is conservative, commonplace, and where leftist opposition should be laser-focused.
