For me, it’s a provider installed ONT on the side of the house. This converts fiber to Ethernet that runs inside my house. I then have just a port to plug my router into.

Now, the provider trying to bundle a router is another question… but the ONT isn’t something I’d like to buy. And on my invoice, it isn’t even listed as something that I rent.

I'm in Poland. When I had fiber installed I asked the provider if they could install an ONT. They balked a bit but eventually relented. They provided their own ONT at no extra cost. Orange is the provider, in case anyone is interested. It's up to the discretion of the installer. I think being able to speak in technical terms and provide a decent argument convinced the installer. I got a feeling that they don't genera…

Just for the record I've seen other providers giving routers with GPON SFP/XGS-PON SFP+ modules, which act as an ONT (see eg. https://www.play.pl/pomoc/naprawa-i-konfiguracja/telewizja-i...).

I'm not sure if they could be inserted into own equipment, though.

The ONT's job is to translate from (typically) Ethernet to the optical fibre, and nothing else. In networking terms its "Level 1"; concerned only with moving bits from one end to the other. Most ISPs will provide an ONT which does that and nothing else, and then a regular router/firewall that plugs in to the ONT via Ethernet. Your security barrier is the firewall in the router, plus whatever encryption you apply to c…

In Portugal you have at least two ISP’s that do ONT and router in the same device (MEO and Vodafone).

I don’t know what privacy you think you are gaining with your own modem.

They already have your name, address, and payment info.

If you are concerned about them seeing your traffic, well they are going to see that regardless if you use their modem or your own. They own the public IP you get assigned, all traffic is going through their route tables and equipment and is logged before it hits your home router.

Use DNS over https (not the ISPs DNS), or a VPN if you want to hide your activity from them.

Your own modem gains you little in privacy. At worst they could be tracking a count of your devices and their MAC address, but they probably don’t care to collect that.

In my market you can’t plug into the ONT because it still requires authentication.

The modem the ISP provides has hard coded settings to limit connection counts as well as rate limit and probably other things. There is a reason they sell full duplex gigabit for so cheap, there are gremlins in the hardware.

When I explored this question a few months back, I initially thought it was to extract rent. It seems though that it comes from concerns of malfunctioning ONUs, ones that perform poorly, or those that color outside the lines of the specs causing problems on the entire PON node. It seems these concerns were originally well-founded, so the advice has been to match OLT and ONU manufacturers. Now XG-PON ONUs that you can buy are all standards-compliant, so this isn’t really a concern. However, organizations that have been burned by something in the past develop scar tissue over certain topics (“policy”), and say “never again.” I believe that’s probably what is happening here.

Get a business line and you can do whatever you want after the demarc. Unifi probably sells a decent prosumer ONT.

AT&T effectively has two levels of "business line", largely based on the local infra deployment. In a commercial building you'll often be able to just get a fiber drop you can plug into your own SFP, set your IP info, and go. If you do "business line" in a residential area, it's practically the same service as residential Internet with their 802.1x-locked gateways just with static IPs as an option and an actual SLA. Unless you want them to run a fiber from their business service area all the way to your home, but be prepared to spend many thousands more.
