I have my own, because the idea of paying $5/month at the time seemed silly. It does seem like more and more, ISPs are trying to make it harder to bring your own modem, which feels like a cash grab.
Even 10 years ago with Comcast I’d have to call them and challenge their gaslighting to get it working. The model I had was listed on their website, but they would tell me it wasn’t supported. About once a year they would kill it and I had to call to get it working again, where they would again tell me it wasn’t supported, but with persistence on my part, they’d eventually register it and get it working again. I haven’t had as many issue with this recently with Comcast, but I figure it’s only a matter of time.
