This is rather strange if it is accurate. Everywhere I've worked where they hired contractors as developers, the company always preferred contract-to-hire, assuming the person worked out well. I've had two jobs that way, 6-12 month contract to full-time regular employee. The only time people didn't transition to full-time is if they sucked, basically a 6-month interview. And sometimes they would go full-time even if they did suck.
