In a startup it's easy to see what value you added for the user every day. In a megacorp it's impossible. In a startup having the managers ask "what did we do for the users today?" helps the whole team stay on track. In a megacorp it's a useless platitude.
It’s perfectly fine (good even) to work in a large company where your value add is not immediately clarified and is just part of a large agglomerated process. Most net benefit to consumers occurs this way.
It’s also fine if you want to work in the start-up manner, but it’s not “better” or “more correct” or anything.
The author is taking it to a deeply unreasonable extreme that shows more about the author’s arrogance than about any sincere or earnest desire to help customers.
It's very difficult to change perspective once you've worked in one paradigm for a while (at least I find it so - I'm a terrible employee because I've been a freelancer and co-founder for so long). I agree, one is not objectively "better" or "more correct", but that can be a subjective opinion of a blog article author.
