Much worse, it is not just closed-source & but also is shareware/trialware software.[1]

JFTR, I'm using some closed-source apps/games, BUT only if it is unrestricted freeware software.[2]

Talking about simulators, under Linux I use freeware YS Flight Simulator (aka YSFlight)[3], because it is lightweight in comparison to very powerful FlightGear, which is one of the best examples of FLOSS simulators for pilots training[4].

Indeed, but this one is very much a game. Having played it, I can tell you it's fun but a bit shallow.

you reckon drug dealers train using the sim?
