Many people seem weirdly suspicious about Google's #Brotli compression while being weirdly chill about Facebook's #ZSTD, to the point of commenting on posts about Brotli compression being added to things to the effect of, "This is a conspiracy by Google, they clearly should've chosen ZSTD instead". What's up with that? Is Google really so much less scary than 𝘍𝘢𝘤𝘦𝘣𝘰𝘰𝘬?

(This is a subtweet about a certain HN post about Brotli compression coming to #PDF)
