The TSA isn't. The TSA articles are. They have almost nothing to do with startups, and even less to do with tech. They are the antithesis of intellectually interesting.
Startups can be very hacker-oriented, however forming a startup to sell out to a large corp. in the end is very anti-hacker in my opinion. But you don't see people complaining about every startup article on the site. The reality seems to be that the site attracts a cross section of visitors.
Resisting unjust searches and ridiculous security theatre procedures is hacking. The fact that it is also political is irrelevant. I have a hard time understanding a mentality where these issues are not considered interesting or important as they affect our most basic rights. Is your startup or your tech really worth anything without freedom?
