Unfortunately, Wikipedia doesn't seem interested in this. Their revenue is more than enough be able to invest and sustain the site forever, but they just increase expenses on non-core outgoings https://en.wikipedia.org/wiki/WP:CANCER
It's not a bad strategy. I've looked at Wikimedia's financial statements and have no problem giving a small monthly amount to them considering how much value I get from the site.
I certainly prefer my money going to them than to Zuckerberg or Altman or MSFT shareholders.
If you look at revenue vs spend they are net positive by about 7mm last year.
The fluff is important to have a engaged super users. It is also important to get acceptance in certain circles.
It just seems like every wiki results in defensive mod cabals
