I would have liked to see a bit more of 5 Whys here. It seems like a consistent lesson that startups have to learn over and over is how to manage external dependencies, and particularly the dangers of having Google as a dependency. This is new Chrom(e|ium) behavior, and it has a real cost, both for this company and for users, which may or may not be worth the ROI, but this is what happens when you have a large scale external dependency: stuff moves without your knowledge, consent, or control.
Instead of Always. Be. Closing. it should be Always. Be. Mitigating. Dependencies. for startups.
