Also
* they actively promote network neutrality
* their fiber offering is just plain ethernet, so if you have a switch with an SFP slot, that's all you need (well aside of whatever you use as a router - but in my case, that's a VM running PFSense - you're totally free to chose whatever you want). Fewer moving parts means fewer issues.
* they hand out native IPv6 addresses and if you ask them, even a static prefix (for free)
* if you get a static prefix, they even delegate the ip6.arpa zone for reverse lookups
* total soft-factor: their support people use Dovecot Mail under Linux and their press releases are written in Libre Office
Disclaimer I have no relationship with them aside of being a very, very happy customer and I once brought them two bottles of whisky as a thanks for being really quick to set it up for me after I waited a long time for the electrician to put the fiber in my apartment.
