Breaks some subdomain certs (wildcard doesn't cover *.old.reddit.com), causes links you send to others to not honor their preference, and causes links you follow to default to new Reddit (unless you also run a redirection extension).

I've even found that the apartment building that my friend lives in has an elevator that the button _does_ actually work.

But then you have to keep diverting over to old.reddit.com, when a bunch of links go to either www.reddit.com or np.reddit.com or whatever.

Boom.

The fact that you need a browser add-on is very telling about the quality of the website.

it's definitely worth the inconvenience
