I'm not on PON, but on DOCSIS cable, the advantage to using my own modem is:
1. When it breaks, I don't have to wait for weeks for the cable company to send someone to replace it. I just keep a spare on my shelf and can be back up in minutes.
2. Cost: buying my own pays for itself in 6 months.
3. Disintegration: This is more recent, but I've heard from neighbors that the cable company lately doesn't want to rent a modem, only an integrated WAP/router/modem.
