Examples of mission statements that don't produce revenue: Google, Facebook, YouTube, TikTok, most news organizations.
Microsoft's missions in 1980 was "A computer on every desk and in every home". Their mission produced revenue. There are lots of examples of mission/revenue alignment.
The following statements are true but not very interesting:
Microsoft was never about computers on every desk and in every home, it was really about selling software licenses to make money!
The Super Bowl was never about football, it was really about selling ads to makes money!
Wal-Mart was never about saving people money so they could live better, it was really about selling physical items at retail to make money!
Facebook was never about connecting people, it was really about selling ads to make money!
Is the Facebook one any more insightful because the monetization strategy is advertising?
And how would they have made money without lots of computers on lots of desks paying subscriptions?
All companies exist to make money, that’s the point.
X === make money. Y === sell something to make money. Z === make money.
I’m really struggling to understand your point.
For example, Facebook isn't really about connecting people, but a hypothetical competitor with the exact same feature set that charged a subscription fee instead of running ads would be about connecting people?
