I do think it would incentivize new security products/libraries/services focused on helping companies fulfill their security requirements instead of rolling their own crappy solutions.
If a startup cannot secure their customer’s data effectively, I don’t want their product to exist. If that means fewer startups get products off the ground, I fail to see that as a bad thing if a lack of security was the reason.
Slowing the industry down after a decade of breach after breach after breach seems like a reasonable and possible necessary intervention.
