I don't think it's just the media context of the TYSSE that makes it less criticized. It's also the fact that:
1) It doesn't involve abandoning a functional piece of grade separated infrastructure to build along an alternative route in the most expensive way possible to get to the exact same place for $3.5 billion dollars.
2) The city of Toronto is paying
$526 million to get a $2.6 billion 6 station 8.6 kilometer extension for TYSSE, whereas it is paying over $1 billion for a $3.56 billion 1 station
6.2 kilometer extension for the SSE.
3) TYSSE didn't have an cancelled alternative plan that involved the Province footing the entire bill
4) TYSSE is a prerequisite for the Finch West LRT
5) TYSSE takes some load off of Yonge-Bloor, whereas SSE adds to it
