alt Hacker News5% of people can't view them, yet 25% of top websites use them?
In what other industry would it be considered acceptable to exclude 5% of visitors/users/clients?

Maybe they offer alternatives to webp for those 5% ?

That's not how it works.
The server declares what versions of media it has, and the client requests a supported media format. The same trick have been used for audio and video for ages too.
Example:
<picture>
<source srcset="a.webp" type="image/webp">
<img src="fallback.jpg">
</picture>Any industry.
e.g. cars - not everyone is physically able to drive books - blind people can't read music - deaf people can't hear
It is a form of 80/20 or 90/10 rule the last small percentage costs as much as the majority.
Not all businesses are attempting to reach a market of "every internet user globally".
Can the 5% view images at all? The number of web crawlers have exploded recently.
I can tell you, I have personally worked with a global corporation and we estimated that for one of their websites, supporting the 3% that we exclude by using “modern standards” would be more costly than the amount of revenue they get from them. So in that case, it was a rational decision. And up to the 10% cut, management just didn’t want to do the extra investment. So if something falls below that 10% threshold, they just don’t care to get it fixed.
