I don't use 25GBit per se. I have it available and am not limited by it in any way. It also includes a fixed /48 IPv6 Prefix where I can also control reverse DNS. I self-host mail, "cloud" storage, photo backup, VPN and private DNS etc. for my family.
It's just that there is no need to artifically limit access to the internet.
You can also have 1Gbit or 10Gbit if your infrastructure at home doesn't profit from 25 Gbit However their infrastructure stays the same as all their switches have 48 25Gbit downstream ports and 2 (or 4 according to the effective usage) 100Gbit uplink ports to their backbone. You will also pay the same monthly price if you choose a slower line as all their expenses stay the same (except the optics, which you pay as a sign up fee)
They have pretty good peering with many other ISPs and providers and also host cache nodes from the different content providers.
The price is 777 CHF per year since > 10 years (about 75 USD per Month). The bandwidth was increased from 1 to 10 to 25 Gbit while the price stays the same. You only have to pay a upgrade fee of 90 USD for someone to go out to the PoP and change the optics if you upgrade.
I think what you are talking about is consumer ISPs charging for peering (for example DTAG aka Deutsche Telekom is doing this double extortion scheme where they charge their customers and then charge netflix, meta etc. for their traffic too).
Swisscom (biggest ISP in switzerland) tried to charge init7 for peering with this scheme but init7 went to court and won that peering has to stay free (no charge for traffic) for net neutrality. This prevents that swisscom can push out competitors and make the market a monopoly. (writeup if you are interested about this scheme init7 calls it a cartel: https://blog.init7.net/en/to-peer-or-not-to-peer-kartelle-im-internet/ )
The price is 777 CHF per year since > 10 years (about 75 USD per Month).
They also have a pretty new cheaper option aka Easy7 which uses CGNAT (they are a "new" ISP and don't have that much IPv4 space) and fixed IPv6 /56 with 1Gbit for about 50 USD per month.
I just wanted to point out that this market we have in switzerland (and a lot of it was fought for by init7 in court) brings us great options and also is future proof.
