With the current regulation regime, bringing your own modem on spectrum has meant that you give up the ability to get the highest performing tiers. This despite the fact that the modems on the open market were actually better/more capable than the spectrum only modem (aka not available publicly) they were giving people for the gigabit access. (this BTW just recently changed). Even more fun, is that they regularly refuse to provision a modem at its full capability despite your service tier. AKA you have a modem that does X, and a tier that does X, but they will only provision it for 1/2X (and not bother to tell you that). A few years ago I fought a long protracted battle with their support/escalation/etc over a few months to get my modem qualified at the higher tiers and in the end the best excuse they gave was that it was a business decision. AKA, making me upgrade my modem for no technical reason played into their ploy for renting me one.
