What we mean is, you don't have to worry about network transfer when your site gets popular.
You DO still have to worry about plenty of other things though… if your site isn't well optimized and is causing issues for others on your shared server (either because it's pounding the CPU, hogging RAM, or doing tons of disk I/O), you may be asked to sign up for your own Private Server.
Trust us, every host out there has exactly the same limitations… we're just trying to be up front about them!
Basically, sites whose essential purpose is to use disk or bandwidth. When making a website, you should be thinking about "How can I make an interesting site for my visitors while minimizing my server storage, bandwidth, file system, memory, and cpu impact as much as possible?"
The result will be a better experience for your visitors, your web host, and yourself!
