the majority voted to do away with crypto contributions 234 to 94. Some of the main arguments concerned the environmental implications of Bitcoin, the risk of scams, as well as the fact that the WMF gets such a low amount of donations in cryptocurrency compared to other forms of payment
The environmental part is arguably mitigated by other cryptos than Bitcoin, but the others are true for pretty much all of crypto. The low volume of donations in particular is notable to me: people buy cryptocurrencies to hold as a speculative asset, and not to use as a currency.
I do see the mention that Mozilla stopped accepting crypto after backlash, but i don’t think you’re going to be able to pain that backlash as reactionary. And they would have run into the same issues as Wikipedia did regardless of backlash of any kind.
