> Those machines were all sold in 2011 or earlier. Saying "before 2015" is misleading

No, models release before 2015 were deprecated. Same thing with the models of other lines that only had 7 years before being deprecated by macOS.

My point is that, in this context, "models released before 2015" really means "models released before 2012", because there were no MacBook computers on the market between 2012 and 2015. Using the phrasing "released before 2015" implies that there were some MacBooks from 2014 which Apple dropped support for, which is not the case.
