Sure, the Apple deal definitely doesn't help, especially with casuals, but being the recurring punching bag of the league probably has more to do with the current lack of interest with TFC.
Compare this to Vancouver who you would imagine is in a great position to capitalize off the World Cup attention since they are competitive, have a cast of exciting young players, and now this is all supercharged with Muller.
Other teams seem to consistently do well both on & off the pitch with different strategies: good scouting, academies that integrate well with the first team, and/or starpower that actually produces results - e.g. Philly, Seattle, Minnesota, Columbus, Cincinnati, LAFC
Yet somehow TFC currently manage to fail at all of those things!
