Great read, thanks for sharing, going to start digging through that archive, seems like a treasure trove.
Regarding the adoption issues, the FUD is certainly strong. It's unfortunate that there is a mathematically prohibitive roadblock to on chain scaling, as "adopt this technology if you want Bitcoin to survive" is a bit of a user rights snag. Although I guess it is the "right" of a legacy user to remain on legacy technology and pay a fee. Free market economics at its finest.
As for the block weight vs block size, it's just an en-grained habit from trying to explain Bitcoin to others over the years, definitely need to be cognizant of using the correct form in technical discussions. For a layman that is a very subtle/abstract distinction to absorb.
