They buy a service which should block a specific type of traffic, for example bots or attacks. I don't believe any of their customers have purchased a "block a random version of a specific browser" plan. The fact this is occasionally treated as a bug and fixed confirms that idea.
If the customer specifically set a header match to block some Firefox variant, people wouldn't complain to cloudflare about it.
Customers can pick several levels of aggressiveness when it comes to blocking bots. Some of the more obscure browsers easily pass the "low" threshold but don't make it past the "high" threshold. Some older browsers like Palemoon seem to crash or break the JS Cloudflare serves but that seems to be a browser issue.
If your favorite website is blocking you, let them know. They can tweak a lot in their WAF settings. I don't think many websites care about obscure browsers, but it's something websites can control.
That's why I wrote

I'm not sure what point you're trying to make. Cloudflare has been failing this way for ages. At this point they're just accepting it and it affects people who don't understand or care who cloudflare is. It's an issue with cloudflare business model as a whole these days.
