Recognize that nearly everybody is a “dumb bozo”. Most people do not want to manage a home network.
It usually does mean "my network works better".
There are a lot of technically-proficient people who refuse to do this anymore. I guess it is a non-zero amount of work, but it really, really isn't that much. The direction we're headed in is pretty obvious: some day, sooner rather than later, the era of customers being able to use their own cable modems for DOCSIS internet will slowly end, as the people who bother become more and more in the minority.
Nowadays they have to provide PPPoE and voip credentials, and cable providers need to provide a service where you give them the Mac of your own modem and then it gets tied to your contract.

It's somewhat easy if you know network stuff (DNS, DHCP options, CIDR, routing, prefix delegation, etc...); if you somewhat know about those and can navigate some docs the hardest part is figuring out what the ISP expects in terms of magic bits so that it decides to:
a) hand you out v4 address (DHCP) / v6 prefix (RS)
b) allow routing (notably for v6 prefix, sometimes /64 may work OOTB but getting the /48 or /52 you're supposed to have doesn't route without proper RS DHCPv6 options)
c) unlock throttling (some throttle packets unless magic bits are sent in a specific way)
Well; that, and having the proper hardware (e.g obtaining an off-the-shelf 10-GPON SPF module compatible with what your ISP provides might range from very pricey to unobtainium). I'm lucky because my ISP chose a split ONT/router strategy and I just have to plug my own router in the GPON ONT over Ethernet.
† an ISP-provided router is just called a "box" - from "set-top box" - commercial names being "box" concatenated with the ISP initial or name: Bbox, freebox, livebox, neufbox/box SFR
P.S. thanks, now I know why Iliad (Free in Italy is called Iliad) names their router "Iliadbox" :) that naming is not common in Italy

ISPs here are required by law to state the technological standards they use, and consumers can request the required authentication data (for DSL PPPoE) or, in the case of hardware-based authentication with MAC addresses (for DOCSIS), submit these to the provider.
In practice most will rent from their ISP, but the competition is so strong that cheap crap routers are rare, usually ISPs make a point in advertising customers will get an AVM FritzBox - the ultimate market leader for good reasons.

They have a "nerdmode" switch on their website.
