Once a stock is trading on the stock market, buying the products of a company is a better way to support them then buying their stock IMHO. When you buy Tesla stock on the stock market Tesla gets no money from you - you are actually buying the stock from another entity independent from Tesla. Tesla only receives money when the stock is sold for the first time, by the Tesla Corporation to an outsider.
