My understanding is that things are a little more complex than they appear. Take a look at the Tohatsu offerings [1] They offer both 4 stroke and "TLDI" versions of many of their outboards. The TLDI is a two stroke but with updated tech that meets pollution standards and the oil is not mixed with the gas before hand, the oil is mixed with the gas in real time from it's own separate tank with in the motor. Tohatsu is pretty careful not to mention "two stroke" on their site because of its bad connotations from the past.
