It's because the business model for ES is direct competition with AWS and others, and they got out competed. So they had to play licenses games to try and level the field.
It is?
- MongoDB went from AGPL to SSPL
- Redis went from BSD to SSPL
- Elasticsearch went from AGPL to SSPL
- CockroachDB went from Apache to BSL
- TimescaleDB went from Apache to Apache + TLS
- Graylog went from GPL to SSPL

That's why intellectual property law exist. If I spent years writing a book and you were allowed to copy it and sell it then obviously you're going to "out compete" me by default. You didn't incur any costs in producing the thing you're selling, duh!
But other databases don't need it, and stayed truly open source, because their business model doesn't rely on being the only hosting provider.

Indeed, you gave it away for free, saying I could sell it... It doesn't take a business genius to know AWS can undercut your hosting services.
It goes to show that most of these companies don't really care about open source. They cared more about making money and open source was a useful facade to get people to contribute for free.
Exactly. You can sell the products of your work all the way you want.
But pretending to share with the world and then push back when the world actually use it under these same open terms is a hypocrisy.
And even that's overstating it because there's no prohibition of any kind. Cloud providers are free to use SSPL licensed software as long as they release all associated platform code.
After all we're sharing, right?
Other databases are already funded by cloud companies, predate the cloud, or they're too niche to bother.
