It obviously had an impact because reddit wouldn't have taken such draconian action in response. Reddit admins have been forced to show their ass to the public, and many people who previously had positive or neutral opinions of Steve Huffman & co. have now seen what a manipulative, dishonest group they are. They are looking to harvest more user data at a point when no reasonable person would entrust them with this data. They are looking to expand advertising at a point when a significant number of users have either jumped ship or are remaining behind only to actively sabotage the site. More and more people have come to understand that migrating to the fediverse is no big hurdle.

Of course reddit will pay certain outlets to report that the protest has been a failure, but to me it looks like it has been a great success. We knew reddit wouldn't reverse its decision, and we knew it wouldn't just disappear (Digg is still around ffs), but a lot of people have seen that ... reddit the web site never really meant that much to us.
