I don’t know what a .webp file is but I don’t like it. They’re like a filthy prank version of the image/gif you’re looking for. They make you jump through all these hoops to find the original versions of the files that you can actually do anything with.
Well your right I wasn’t clear in my answer. They are open source but for the point of this discussion with open source software backed by an corporation the open source it’s just a mean of spreading “soft power” maybe gather inovation from the market and for sure to offer a way for FOSS creators to use their energies to build in the “correct” direction. The purpose it’s building a monopoly on certain aspects of the market.
Chromium is open source and a lot of small projects have sprouted from it but with the same undelying technology. Except for Firefox, Edge and Safary, everyone stems from the same roots controlled by google trough money and market share. So in this case Chrome dominates the market and decides the course of the industry. See mv3.
Android is open source and some projects are build on top of it but the big market share so the direction of the technology is controlled by Google.
Let them decide a stadard for pictures which has undeniable advantages and I bet you that tomorow they will decide how you share and visualise images and videos.
It’s not about being open source it’s about that project being a tool used by a company to spread their interests (which usually end up being predatory towards the common user).
