The Commons Clause and Redis
Redis has added the Commons Clause to some of its enterprise modules, which were licensed solely under the terms of the AGPL license. The Commons Clause is added on top of the current license and takes away the right to make any money from the software it covers, including consulting and hosting.
Going forward Redis Labs, the company behind Redis, will be the only company making profits of its enterprise modules. However, the new license applies to the enterprise modules only and doesn't affect earlier releases either. The Redis core will stay open source under the terms of the BSD license.
More generally: Open Source business cases
