I was responding to the broader point that security is used as justification for making systems less accessible to programmers.
Apple doesn't distinguish between safe and unsafe languages for now, but it's not impossible to imagine this becoming a restriction in the future, given the broader trend.
The original claim was that "you might not be allowed to program in 'unsafe' languages on all other mainstream platforms". But Apple restrictions don't distinguish between safe and unsafe languages, they just restrict all arbitrary code, so this is not an example of the point being made, but rather an orthogonal issue.
