Redis might be the greatest betrayal in open source history.
In 2009 an Italian developer named Salvatore Sanfilippo was building a startup and MySQL was too slow. So he built his own in-memory database in his spare time and open sourced it for free.
He called it Redis.
Twitter used it. GitHub used it. Snapchat used it. Stack Overflow used it. Every major tech company on earth ran Redis somewhere in their stack.
By 2020 Salvatore was burnt out after 11 years of maintaining it alone. He handed the project to Redis Labs and walked away.
Then in March 2024 Redis Labs changed the license.
Overnight Redis was no longer open source. Cloud providers could no longer offer it as a managed service without paying Redis Labs. The community that built it around Salvatore's code woke up locked out.
They did not argue. They did not write blog posts. They forked it.
Eight days later the Linux Foundation announced Valkey. Backed by AWS, Google, Oracle, Ericsson and Snap. Over 50 companies joined within weeks.
Within a year Fedora, Ubuntu, Debian and Arch all dropped Redis and made Valkey their default. AWS migrated millions of nodes to Valkey. Valkey hit 1.19 million requests per second. 230% faster than the version Redis abandoned.
Then Redis brought Salvatore back to win the community over.
He came back. He showed up on Hacker News defending the license change. He tried to rebuild trust.
The community had already moved on without him.
Redis built 15 years of open source trust. Tested it once. Lost it in 8 days.
In open source the community is not just the users.
The community is the moat.
