The bit about Biz to Airline relates to a lack of familiarity with corporate pilots. Eg there's a world of difference between a private ops early series Cessna 500 and a large organisation with "airline style" SOPs, oversight, manuals, simulator training etc.
I've found when talking to folks who only know "airline ops" that they have a very limited and often incorrect perception of biz jet pilots. However, as biz jet pilots move into airlines that perception is fading.
