I will answer to the end of your email only as it shocked me.
No doubt the architects of this development will eventually leave the WMF with résumés highlighting by how much they increased revenue over such-and-such an amount of time, how they built a $100M endowment in half the time planned (this target was achieved five years early), and move to a different employer who values these abilities.
This is totally out of place. First of, it's their work and praising on their achievements is nothing shameful. I hope they see their work as good work.
Second, the Fundraising team is made of deeply engaged people. I will not list them all, but I am pretty sure that teams have some of the "older" employees in the Foundation. If you take the three first names of the staff list, the three (Lisa, Megan and Guillaume) all have been at the Foundation for over 10 years.
So your attack is out of place, unfounded and totally wrong. They are staff, they are professionals, they are highly engaged people and part of our movement as we all are.
So please, stop attacking people.
