FWIW, the last time Apple released a new product with the prefix “i” was the iPad in 2010. They favour “Apple” now, as in “Apple Watch”, “Apple TV”, and “Apple Vision Pro”.
They found that you can’t copyright/trademark “i” as a prefix in and of itself. That means that while nobody else can bring out a product called “iPhone” or “iPod”, they absolutely can bring out a product called, say, “iLaptop”. And that’s what people did for all kinds of products, hoping that people would buy them, mistakenly thinking they were Apple products.
So Apple abandoned it as branding on everything that wasn’t already well-known for that branding.
Your point is right in spirit, but wrong on that one specific point.
I’ve also seen it said by people who know more about this kind of thing than i do that because they’re relatively rare forks like librewolf actually make identifying individual users easier than if you were using vanilla Firefox
