I don't understand the argument here. If your company had hosting costs increase this much and said "hey sien, we're going to cover the costs by cutting your salary" I don't think you'd be thrilled. Non-profits have staff and they have to pay them.
Being the devil's advocate, there are are quite a lot of smaller non-profits that are entirely volunteer-run. While Wikipedia's mission might inherently be big enough to merit a few salaried employees, I can't fathom why they need so many. As per Wilde's famous quip, it seems to me that "the bureaucracy is expanding to meet the needs of the expanding bureaucracy".
Honestly, just don’t. The world doesn’t really need hypothetical antagonism anymore.
