They own the entire .dev gTLD namespace - they aren't hiding it, but it's probably not common knowledge.
I am not defending Google behavior, I have no dog in this fight, just sharing. In fact, there was a weird behavior I detected inadvertently last year 2 employers ago where I couldn't load any .dev public internet sites due to preloaded rules that hadn't been updated since before the .dev gTLD was publicly available. Some would load, and others (web.dev in particular) wouldn't load. Anyways yeah this sucks, it seems that any new advancements in web related technologies that could enable new privacy measures are just side stepped by the dark wizards out of Mountain View...
