I can get behind that. Not to protect myself from wifi radiation, but to cut down on the amount of wifi traffic interfering with my signal. There are only 13 usable channels in 2.4Ghz, and I don't feel like replacing my router for 5Ghz right away.
In the US, there are 11 channels, and either 3 or (with cooperation and planning between neighbors) 4 non-overlapping channels. Investing in 5ghz was the only way I could get a decent signal in my high-rise apartment.
