Thousands of Reddit communities will stop being accessible tomorrow in protest against the decision to charge millions of dollars to apps that use the API. As a result of the policy, many apps will stop working.
However, while some people are recommending that people stop using Reddit, the protest is limited to two days. The problem with doing a temporary boycott is that it sends this message to the owners: a lot of people are angry, but after two days they're going to come back and we're going to keep making money. Reddit stopped being free software years ago and it's not going to stop censoring information they don't like.
I support boycotting Reddit, but I think it shouldn't just last two days; it should be permanent. There are several programs similar to Reddit that are free and respect the privacy of their users: Lemmy, /kbin, Postmill, Lobsters, Tildes...
Lemmy and /kbin, unlike Reddit, are free and federated, so the administrators of a node cannot censor information from nodes they don't control or impose anything on them; each node has its own policy.
