The article linked above has a good summery (emphasise added):
If you’re not yet aware of the SSPL, you can catch up here. As licenses go, it’s pretty problematic from a business perspective. Every IP lawyer to whom I’ve showed the text of the SSPL has been rather alarmed before they even reach the end of it. Basically, it’s a hostile proprietary license masquerading in open source clothing.
There is a Hacker News thread on this here.
- Keep using the last last version under Apache terms.
- Pay for a commercial license.
- A hard fork based on the last version under Apache terms (which could be open or closed).
Of course there are other options, if Amazon was a better player in the free / open source community it would perhaps follow the approach that RedHat has used in the past, buying companies / projects and then applying the GPL to the code (for example Ansible), but given their history this seems very unlikely…
