I'm not involved in any package manager development, but this strikes me as extremely arrogant. Successful package managers are most definitely not a dime a dozen, and the skills required to make one and maintain it over years are something which the majority of engineers at Google (or anywhere) do not possess. There's a lot more to software engineering than working on the hardest of the hard tech problems, and being very successful on the social side is a huge asset that no company should discount based on the theoretical difficulty of the problem being solved.
