Once again, the old KGB saying "they pretend to pay us, and we pretend to work" can still be found in the post-communist world.
Once again, my blog post about this is relevant here.
There is a thread about a similar article that discusses how Fidelity investments is being pressured to try to pressure the bitcoin devs to switch to PoS. I noted that many investment management companies often push their own political and social agenda while threatening to vote a particular way with shares that belong to their customers. Noted in your blog post is that there are a small number of exchanges that stake coin on behalf of their customers.
If a change to PoS is done, it would be best to not do so for reasons related to "climate change".
From the technical side, I am not convinced that PoS is equivalent in security, let alone better than, PoW. The NaS issue hasn't been answered to my understanding.
