What does worry me is that less page views may mean less engagement in the form of checking sources, flagging problems, and making edits.
But the number of new registered users and the number of user edits are both decreasing: https://stats.wikimedia.org/#/all-projects
tl;dr
The monetary cost does not really matter
1. It does contribute money, which Wikimedia does not need.
No.
At some point in an encyclopedia's lifetime, it's "complete enough" that you'll see an excess of authors. "Compiling the world's information" and, past that, "compiling current events as they happen" (with a side of "occasionally improving/updating old articles") need very different numbers of authors.
This is based off the fact that I frequently see:
- "why does X not have a Wikipedia article?"
- "this Wikipedia article is so poorly written"
And very rarely actually see someone edit it. On occasion thousands of people have agreed and hundreds of people have written comments agreeing and only two people edited.
So maybe it does some damage at the margin but overall probably doesn't hurt that much.
Up until now, an edit was one click away. Now, it's not only one more click away but wikipedia has no way to communicate that editing the result is possible at all.
And it doesn't change the fact that if you have open content then you have open content.
If you compare Wikimedias spending 5 years ago to what it is now, it has ballooned in such an excessive way if you put it in context. Wikipedia isn't providing double the value of what it was 5 years ago.
Surely it's "worth it" if you want the site to be usable by novice users. This is about optimizing for reach and intellectual diversity, not just "people who are currently adding value".
> Wikipedia isn't providing double the value of what it was 5 years ago.
Wikimedia supports other projects besides Wikipedia itself, and the value it provides has not just doubled but plausibly grown by an order of magnitude compared to its early days. Wikimedia Commons and Wikidata are hugely beneficial to the Internet community, and Wikivoyage is not far behind.
Maybe this wouldn't be the case if pages were less complicated to edit?
