I hate to defend Amazon, but it seems that they do contribute back to open source:

https://aws.amazon.com/opensource/

For example running `git shortlog -ne` in the Linux kernel git repository will show a number of Amazon folks with many commits to their name.

Linux contributions are not the best example, since it's GPL, and you pretty much have to contribute back to get your changes mainlined, and end-users can request your changes at any time.

Now, if they contributed back to FreeBSD, that would be meaningful, since they don't have to.

[pabs3]

Amazon doesn't distribute Linux on server hardware (just consumer hardware like the Kindle) so they don't have to give back for server aspects of Linux like KVM, yet in the Linux kernel code, the Amazon employees are mostly submitting patches for things like KVM, not for Kindle hardware support.

It would surprise me if Amazon use FreeBSD, I thought they use Xen & Linux KVM exclusively?

Disclosure: I work for AWS.

See https://twitter.com/cperciva/status/1211125881264934917 for one example of working with FreeBSD.

  It's truly awesome that I can send an email to Amazon 
  saying "we're seeing an odd performance issue here" and
  get back "here's a FreeBSD kernel patch I just wrote which
  provides a 10% performance boost".
  
  And people claim that Amazon never contributes back to
  open source...

I linked the patches here. Not all of the work is from an AWS engineer: https://twitter.com/_msw_/status/1220088310443307008

Those are not the same open source projects.

When Amazon strip mines and destroys some projects, I don't think that's any better just because they need and do changes in the kernel

[pabs3]

Do you have any examples of projects destroyed by Amazon? Or a definition of what you mean by "strip mine"?

[cutemonster]

"strip mine" is in the zdnet article linked above, have a look. (Resells without contributing back in any meaningful way, instead hurting the oss company financially).

"Destroyed" was an exaggeration, at least as of today.

However I like and use some of the oss projects Amazon strip mines -- if Amazon instead paid the oss companies a part of want Amazon makes, that'd let those oss projects hire more people, improve the software even more -- and that I would appreciate, and could be made in a mutually beneficial way I think.

This isn't a new problem, for eg web hosting companies have been selling Apache/PHP hosting for decades. Apache and PHP were made more useful because of that reselling rather than being negatively affected by it. I think the only difference now is these OSS companies are VC backed so they have to get huge growth to pay back their giant loans.

I watched a talk recently that argued that Amazon increases the size of the market available for the software the OSS companies are producing. So the pie increases in size and the result is likely to be more money available for the software, not less.

The OSS companies you refer to are more about using OSS as the new shareware, a loss leader or poison pill to sell proprietary software, their business model isn't about open source at all.

> 'the only difference now is these OSS companies are VC backed so they have to get huge growth'

That's a good point.

> their business model isn't about open source at all.

(What do you consider open source biz models?)

> OSS as the new shareware

I think I understand what you mean. At the same time, in my case using only the OSS parts of the open core software, has been more than what I've needed

> I watched a talk recently

That talk sounds interesting, ... If you remember the name or speaker maybe I can find it?

[pabs3]

> What do you consider open source biz models?

Something that doesn't involve proprietary software, so support or pure-OSS SaaSS. Like RedHat.

> If you remember the name or speaker maybe I can find it?

I think it may have been one by either NextCloud or RedHat, I'll try to find it.

Have they contributed to MySQL/MariaDB or to Postgres?

[pabs3]

The Postgres git repo doesn't make it easy to discover the employer of the commit authors, but yes, they do send patches to Postgres, here is a search of commits referencing mailing list discussions started by Amazon, plus a couple of examples of where they sent patches:
