I must be failing to understand your comment. The people complaining are FSF, and no matter how hard I squint, I cannot see how fair competition could require Google to be the first one to support a standard that literally nobody else supports.
Nope, not just FSF. The Chromium team have prototyped JXL, but removed it initially for unknown reasons (https://bugs.chromium.org/p/chromium/issues/detail?id=117805...). Engineering teams including but not limited to Adobe, Facebook, Intel and Shopify have complained about its abrupt removal. Chromium developers have subsequently said that it was "due to low interest" (despite piles of messages from engineering teams both in leading companies and small groups saying otherwise).

First, Adobe products have just included JXL. Second, It's because Google is pushing for AVIF, which was extended from AV1. While it has some advantages (as essentially extended version from AV1), it also has a lot of disadvantages: https://news.ycombinator.com/item?id=35590516. No one said to remove AVIF in favor of JXL and in fact there are instances where AVIF is the better choice (animated images due to its interframe support) but instead to support JXL regardless of Google's support of AVIF, and some people have seen it as forcing Google-favored AVIF instead of considering all formats developed (like how WebP was rammed a decade ago).
There's also the more widespread phenomenon of profitable-enough local businesses blaming Walmart for putting them out of business. How do we evaluate which analogy is appropriate?
