A toss up between Apple and Microsoft...

Apple I use to love because I used an iPhone exclusively and loved iOS but the more and more I moved into the cloud. The more and more I started hating the lack of online tools like word processing and the like so eventually led me to disliking them but now I hate them exclusively because of there hardware fragmentation, the lack of consistency between there hardware really irritates me...

And Microsoft came from in an instant, I use to love windows and use it exclusively but as soon as I discovered Linux and got my first taste of it through Ubuntu I started hating windows compared to Linux but now I hate the company because of their two faced ways, will state they support the open source community yet only throw actual support when they clearly can't be beaten and give in...

(Can feel the hate coming my way so all good!)
