Because I have not found TEA to be a better activator than, e.g. sodium metaborate. I have found it a lot easier to throw a teaspoon of metaborate (or 5 ml of a stock liquid solution if you use Gainer's recipe for creating metaborate from borax and lye) into a liter of water containing some Phenidone-ascorbic acid stock than to go through the mess (and smell!) of heating TEA in order to dissolve the chemicals.
