Yes. As someone who uses both, this is a M$ problem.

We of the privileged Linux class.

Yeah, same here. No problem with webp on Linux Mint.

I guess it's Windows users with the default image viewer. IrfanView on W10 handles webp fine for me.

It’s an everywhere problem. A lot of sites and apps still don’t support it, but a most browsers do. So people download images from their browser, then they try to view / edit locally, or upload and share, and they hit a wall.

I’m too Linux to understand?

The advantage of using shared libraries is that you only need the one to support webp system-wide and then all apps that need it have it.

yes, because we just have 1 good libwebp library
