This applies only for a diminishingly small amount of large corporations and is not applicable to absolute majority of HN startups/bootstraps/side projects.
Bootstrappers (when they are small) and side projects can ignore the smaller percentages because they are still validating their concepts. For side projects this goes even more because they are usually not commercial in nature.
Why would it have to be applicable to the 'absolute majority of HN startups/bootstraps/side projects' to be useful information?
