Given that this came from Facebook it basically has the validity equivalent of what the drunk homeless man who's wet himself shouts in the street... actually, comparing Facebook to him is an insult to the homeless man
*Rotax will eventually build larger and larger more powerful, and certified engines for aircraft.. it's just the natural course of evolution. It will take a while, but with EA thriving (relatively) there is a (albeit small) market for this
PS - in the 0.000001% chance that this is infact true, then clearly Rotax at the time thought it made sense financially, as did Lycoming. As someone else stated there is a very small market for 300hp aircraft engines... it's basically Cirrus (if we look at any kind of volume). Knowing that Cirrus is at the more advanced edge of the envelope and Lycos now being put in the SR20 they may have felt this was some good intellectual property to have to eventually, one day, push out Lyco or give buyers a choice (like Boeing / Airbus give a choice, on some models, between PW, RR, GE, etc.)
PPS - even if Conti / Cirrus have the same (or similar) financiers the world economic forces are still demand and $$ driven.. if someone builds a better mousetrap than the existing 300+ hp conti used that can be had for similar or less price point with the "proven" reliability I doubt they'd put an inferior product into a plane, and continue to do so
