More than 300 subreddits, including popular ones like r/aww, r/music r/videos, and r/futurology, plan to go dark indefinitely after a large protest against Reddit’s API changes ends on June 14. This means users won’t be able to access these communities during this blackout.

This step was announced after The Verge reported that in an internal memo, Reddit CEO Steve Huffman said “Like all blowups on Reddit, this one will pass as well”. Huffman said in the memo that the blackout hasn’t caused any significant impact on the company’s revenue.
