Look at railway electrification: this has been happening since the late 1800s; in 2012 electric railways only accounted for 1/3 of the world's tracks. Point being: decarbonisation typically does not happen overnight, and this shouldn't stop us from decrying an entire technology.

The scale of ETH's decarbonisation feels slow by our typical software standards (although it is not a single piece of versioned software nor owned by a single company) - but shorter relative to some other global-scale decarbonisation efforts; it is slated to merge this year.

No matter... there is no need to engage with PoW if this is your primary concern. If desired, Mozilla could have led a stronger force toward PoS chains by only accepting crypto donations in (say) Tezos, rather than just closing the possibility of donations entirely.
