If you look at the issue tracker, the creator of Webp killed it because of untrue claims there was no interest or advantages over existing formats.
Concerns about the implementation only came up after years of pushback forced google ton reconsider.

I think for most modern software it's difficult to name the creator, but if you had to for webp, it would be hard to argue that it's anyone but Jyrki Alakuijala, who is in fact one of the co-creators of jpegxl and the person backing up the long-term support of the rust jxl-rs implementation, so I'm not even going to ask for a source here because it's just not true.
AFAIK Jyrki came after WebP was already announced to add lossless support; rather I’d consider Skal the creator inasmuch as it was originally just an image container for VP8 intra. He was working on WebP2 at the time Google rejected JPEG-XL and also was not involved in that decision.
I designed the lossless format and its initial encoder. Zoltán Szabadka wrote the initial lossless decoder.
On2 Technologies had designed the lossy format and its initial encoder/decoder. Skal improved on the encoder (rewriting it for better quality, inventing workarounds for the YUV420 sampling quality issues), but did not change the format's image-related aspects that On2 Technologies had come up with for VP8 video use.
In the end stage of lossless productization (around February 2012) Skal had minor impact on the lossless format:
1. He asked it to have the same size limitations (16383x16383 pixels) like lossy.
2. He wanted to remove some expressivity for easier time for hardware implementations, perhaps a 0.5 % hit on density.
Skal also took care of integrating the lossless format into the lossy as an alpha layer.
>so I'm not even going to ask for a source here because it's just not true.
Well it is up to you to decide. The link was submitted a dozen of times on HN and the whole thing was well reported. And Jyrki Alakuijala already classify its creator status.
It's been 3 years, I might have people mixed up, but that was the justification at the time.
