I'm not sure anyone has actually stated they wanted to see MLS/TFC fold. It is possible to infer from some of the statements, that some are not exactly rooting for the league but few really wish the league to collapse. Most of us are cautioning that the continued success of the league can't be based on exorbitant expansion fees, as that will lead to eventual disaster.
With the hugely disappointing TV ratings for the MLS Cup and the majority of the teams losing money, relying on expansion fees to keep teams afloat, is not a sound business model. What many of us are urging, is for the league, not to over reach with rapid expansion but rather take a more prudent approach to the growth of the league.
Many want to see both the Argos and TFC being successful on the field and on the books but this can only happen if MLS is put on sound financial footing and depending on what appears to be inflated expansion fees, could well blow up in the league's face sooner or later.
