npub1hyp0snlqyw66uwuep7tnkwqhgpg7qspvf928v0mm8d9penuwee0srvaehm (npub1hyp…aehm) CEO of a company selling bad quality printers at loss to recover on 10-100x ink costs blames counterfeit ink cartridges for causing "insert random or imaginary security issue" and uses it as a excuse to lock down the ink DRM on printers. That sounds more credible than the attack to printers through cartridges.
But to be fair, there's a massive amount of research being done by counterfeit ink companies to reverse engineer and break their DRM. They go as far as chip decap + ROM extraction to copy the secrets.
