Who cares? There’s virtually infinite opportunities for domain names - unless you think there are better, more legitimate uses for the phrase “are we audio yet?” And it’s not like domain abandonment isn’t already handled by ICANN.
When I click a link, I want to know where I'm going. Where do you think "arewesmoothyet.com" will take you? If you guessed some Mozilla related thing purely from context, well you're also wrong. It's actually some WFH/affiliate marketing course. This was my point; domains are expensive and temporary for people who don't care. Because of this stupid joke, people actually interested in "Firefox Nightly hang telemetry visualization" or whatever have nowhere to go. One wiki, one page per topic, is all you need.
