Let's say you have two file formats. One is a open standard, the other one is not (but has it's specifications published, that's something at least). Both formats have the same purpose and basically works the same way. One has been around for almost 20 years, the other for around 9 years (but specification not open until 2 years after release).

Instead of going for the one with the open standard, that does the same thing, Apple prefers to invent their own format, that they can change at their own whim and that they now can optimize their hardware for, so they get an advantage no one else can use.

You don't see anything bad in this? Are you really arguing against open standards? I thought we went through this with the internet and the web already, and open standards is something people generally prefer. It just ends up better for everyone, instead of companies inventing their own formats time and time again, especially when a format that suits their needs already exists...
