I really don't see how Amazon is to blame for this problem, they weren't the ones who picked the license.

They both sell it for profit, let the most profitable one win.

Because parasitic antisocial behavior is viewed negatively.

Trying to apply market dynamics to selling things you didn't produce (or pay for) is fascinating...

They both sell it for profit, but Amazon doesn’t contribute changes upstream, so the public + rest of the industry won’t benefit from their work. It’s not an equivalence.

Because you don't see AWS as having sort of moral or ethical duties. I see all companies and people as having moral and ethical duties.

Why isn't this a problem for other databases then? I'm sure most cloud sell some MariaDB services. Why would they be able to profit from it?

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!

Yes and the result is these databases got forked, and the community got rightfully mad.

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.

> You didn't incur any costs in producing the thing you're selling, duh!

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.
