Even when the intrusion is small, it is ridiculous because it is not required for the software to work (e.g. in the iPhone SETTINGS app, nothing about tweaking settings ever requires the user to view a stupid ad, and yet there they are, crappifying the UI).
And as I get older I am telling myself “this isn’t what I signed up for”: I want useful software that is free of garbage, especially when money is exchanged, and most certainly when a LOT of money is exchanged.
So tell these bean-counters to get the hell out, and let us make computers “only” useful instead of ad-spewing machines.
