A similar ISP, very much alive and kicking, is https://www.init7.net/en/ in Switzerland. In particular, with their fiber7 brand (see https://www.init7.net/en/internet/fiber7/), they tick all the boxes mentioned in the article: no caps, fully symmetrical gigabit fiber, ISP actively promoting and pushing net neutrality, ISP actively engaged politically, very knowledgable support staff, etc.
