ActivityPub vs AT Protocol: open letter

An open letter trying to calm troubled protocol waters: "the Social Web Community Group has seen an increase in heated discussions online ... a hotbed for conflict, disagreements, and misinformation. There has often been significant biases exhibited within these conversations."

Points out that the 2 protocols have more in common than what divides them, and "There does not have to be a “winning” protocol. We do not build a better open social web for everyone by fighting ... only emboldens those that seek to derail and destroy efforts to build an open social web."

What I didn't know:

• "AT Protocol adopted an internet draft that was originally written to support the ActivityPub ecosystem...
• projects within ActivityPub have adopted some ideas on content labeling and starter packs from the AT Protocol ecosystem.
