Chill out and get Nova launcher ;-)
Excellent advice.
You may find TouchWiz horrific but a lot of people find it to be quite useful, and even more so once you dig into its various options to suit your own needs. Also, nobody is forcing you to buy a Samsung device, there are numerous options available to you, that's one of the big advantages of the Android ecosystem, lots of choice to suit your needs.
Also, if you're going to reach out to Ssmsung in some kind of protest, note that TouchWiz has been renamed to 'Samsung Experience'.
