That's kind of like saying places that suffer from dine-and-dashers suffer from a service problem. I disagree.
Some services can sustain subsidization. Google can "give out" GMail, people will be happy to have the service for "free". Smaller players who can't subsidize their service(s) with ad platforms may have to either charge money or offer fewer features and recoup revenue via features.
Gabe has the breadth and resources to practice his economics -many others do too; however, many smaller or more focused players don't have that liberty. Obviously we have companies who go to extremes to ruthlessly extract as much as they can from their customers. They are obviously deserving of criticism --but not everyone who wants can play by Gabe's philosophy.
