I don't get why people are so angered by this.
First of all - how many AAA videogames do you need to have installed at once?
And second of all, if for some reason it's around 10, how long do you think it will be a standard to have, say, a 1TB disk in your computer? That's what we put in them ten years back. You can buy an SSD(!) of this size for laughable prices today, so what's the big whoop? Just buy two of them.

If you get a patch this big on day1, that's a pain, because you unexpectedly can't play your game for a few hours depending on your internet speed. But that's not a problem of games being big, that's them being shipped unfinished.
