My family already uses signal as are default form of communication between each but the point that I forgot to add was for the 1% of conversation. Some of my family member have there own businesses that mostly use email but when we are in the field we use regular SMS/MMS/imessage for quick communication between “us” and the client. At least here we most only use plain SMS or iMessage if applicable is used because most people see messaging apps like Signal, WhatsApp and other third party apps for personal use only.

I should have asked more specifically asking how are they using zstd. I already understand that its a compression algorithm.

Can someone explain,

Firefox now supports Content-encoding: zstd (zstandard compression). This is an alternative to broti and gzip compression for web content, and can provide higher compression levels for the same CPU used, or conversely lower server CPU use to get the same compression. This is heavily used on sites such as Facebook.

what it means for me the user and what it means for the people who host content?
