Does it really matter? the name of the fly-by-night owner that they used ? doubt if any one of those quoted was any better than the other
What matters is that current legislation leaves the unsuspecting pax flying with (supposedly) a "local" (& so proud of that in their ads, weren't they? ) operator,but in reality finds themselves , in the back of a ship owned/operated (perchance both? ) by any Tom, Dick , or Manuel, that offers the lowest price and holds an AOC from anywhere acceptable to a JAR registered operator.
All oranges are NOT the same, for the avoidance of doubt.
