Not open source. Open source is a resounding success. The marketplace with the problems is advertising. We need to enact laws banning selling of third party data and make leaks a liability (perhaps even one that automatically pierces the normal corporate veil and opens VPs and up to personal liability if there was any circumvention initiated encouraged by them). Then businesses have to actually decide if the liability is worth it for them vs a free-for-all market that intelligence agencies and criminal enterprises are primarily funding.
