The Wikimedia Foundation has decided to discontinue direct acceptance of cryptocurrency as a means of donating … we are making this decision based on recent feedback from [volunteers and donor] communities
You could have been quoting a little more from that news.
“Cryptocurrencies are extremely risky investments that have only been gaining popularity among retail investors particularly in recent times, and I do not think we should be endorsing their use in this way. In accepting them, I believe we are mainstreaming the usage of “investments” and technology that are inherently predatory,” the proposal read.
Although I find this overly harsh words against crypto (yet another naysayer), the actual points are clear:
* Wiki seems to have received very few donations in crypto (which is normal, since very small % of world population uses crypto, so it's imho not a valid problem)
* Wiki doesn't want to look like they would be endorsing cryptocurrencies, which actually I cannot argue
However, seeing Wiki as a pretty "hungry" organization - they do put big banners begging for money now and then - I think that's a losing move on their side. Although they've received "only" 130k worth of crypto as donations, it's much better than nothing.
However, it might help wiki collect more donations made in cryptocoins if they endorsed and encouraged their use. Similar to bitcoin, wikipedia live through the collaboration of people around the world who work together as a community in an open environment and without a leader. It should be the wikipedia community that should be recognizing bitcoin as a medium of payment.
