None of this stopped Google's push for WebP or AVIF.
I don't think AVIF is a good example of this though. All major browser makers were members of the consortium that created AVIF.
But it was a tremendous amount of effort and promotion on Google's end for a relatively narrow format.
I'm not a fan of WebP, mind, but the idea that support for it is dreadful is strange to me.
Personally, the fact that it was Googles idea means I’m going to hold it at arms length, if not avoid it entirely. The web should be built on open standards.
Seems to be a similar level of "works everywhere" for me, with the exception of web browsers this time.
