Sure, Zoom has made some design decisions that made sense as a small spunky startup that don't make a lot of sense as a defacto standard, but that's to be expected.

One of the more fundamental rules of building fast websites is to optimise your assets, and where text content such as HTML, CSS, and JS are concerned, we’re talking about compression. The de facto text-compression of the web is Gzip, with around 80% of compressed responses favouring that algorithm, and the remaining 20% use the much newer Brotli. Of course, this total of 100% only measures compressible responses that actually were compressed—there are still many millions of resources that could
