They have long ago eclipsed the cost of running it and now donate/fund causes that are in line with their views.

I think the use of the word "eclipsed" is a a bit odd. Eclipsed in this case, and the literal sense, just means it's covered. In this case, revenue exceeds costs by what, 8%?
We should want the assets to grow significantly. Ideally Wikimedia would have an endowment that is sufficient to grow at a rate to allow the site to be run in perpetuity without any further contributions.
I do not mind that they provide those grants, it is just something to keep in mind.
WP seems to me to be the most cacheable site in existence, I wonder what 100M worth of staff are doing there.
