How is this even worth it to MS?

Do they really expect people who go through the effort of installing a third party browser and setting it as default to switch back to Edge because of the grand experience they had with it when Windows opened some help article in it?

How much money do they make of the 0.000001% of users who do the above?

How much money do they lose because of the reputation damage and increased regulator attention because of it?

I cannot think of any scenario where, money wise, this is a net positive for MS.
