As quoted from the linked post.
It looks like you’re part of one of our experiments. The logged-in mobile web experience is currently unavailable for a portion of users. To access the site you can log on via desktop, the mobile apps, or wait for the experiment to conclude.
This is separate from the API issue. This will actually BLOCK you from even viewing reddit on your phone without using the official app.

Sure I had fun, but was it good for people? Communities of people did good things, not Reddit. Reddit was a great source for hate speech, propaganda, and ads. People did their best to be good in spite of the noise.
Reddit needs to die. People will find each other again, we always do.
