This is not exactly like Apple I think.

This is about printing texts on T-shirt. It is only a small step further from printing texts on a white paper.

Moreover it is about printing a letter in the Greek alphabet that also happens to be a common mathematical symbol.

I can see maybe if the trademark was about very specific font and color combined. They anyone else could just pick a different font. It doesn't seem to like that.

This is NOT about printing texts on a Tshirt. It is about a company trying to brand itself as "pi." (why they would want to do that is beyond me) JUST like Apple branded itself as "Apple" This company will make clothing apparel. This does NOT stop anyone else from putting the symbol pi on a tshirt. You just can't do it in a way that makes it look like you are the "pi." company.
