Question - Can open source code licensed under Apache License 2.0 simply be deleted from a public Github repo by the owner?

Apologies if this is covered elsewhere.

I have visited both the legal FAQ and the specific Apache License FAQ pages
and couldn't see a question that matches this.

I should stress that the code in question was licensed under Apache License
2.0 but has not been contributed to ASF or any other open source project
governed by a foundation.

Anyway to cut to the chase I have just seen a tweet[1] where someone says

I cant seem to find the community version of @scalr is it closed source
> only now. I see the github pages giving 404 errors! #scalrclosed


Basically Scalr's community edition of their software appears to have
disappeared from view. This is in spite of their Wikipedia entry[2] making
it clear that Scalr is open source, freely available under Apache License
2.0 and in Github repo[3].

My understanding was that you can of course stop contributing to an ASL 2.0
project but that you can't simply delete it as you have granted anyone
using it an irrevocable Copyright and Patent license which is hard to use
without the source code.

Is this a correct interpretation of the Apache License 2.0?

No problem, good question.  However we can't give you legal advice, only
layperson's commentary on your questions.  I'm not a lawyer, and these
are merely personal opinions that might be helpful.

Wikipedia is not a legally authoritative source for either their
licensing or the licensing of whoever originally contributed some of the
code.

Strictly from the perspective of the Apache-2.0 license:

Yes, there is no obligation to continue contributions to a repository.

No - repository owners are free to delete their repositories.  There is
no overall requirement in Apache-2.0 that a licensor or licensee must
provide source code, *unless* they are performing acts that are covered
under section 4 of the license:

  https://www.apache.org/licenses/LICENSE-2.0.html#redistribution

If a licensee *is* redistributing, then they need to meet those
conditions.  However they are free to redistribute just objects of their
modifications along with license/notice - there's no obligation to
provide the source code at all.

Obviously, anyone who has legally gotten a copy of the source code -
either in the past, or from some other proper licensor - can still find
the code.

Does that help?

Obviously, deleting previously-published source code from an opensource
licensed project is impolite and not friendly to contributors or the
rest of the ecosystem.  But under Apache-2.0, there is no restriction
from deleting or otherwise stopping the availability of source code
repositories someone owns.

Shane / Greg

Many thanks.

Very useful background.

There are any number of open source projects out there that are not properly governed. Caveat usor.

Forked on GitHub, or maybe you can find a tarball of one of the releases
they made? That tarball will be covered under ALv2, and you can post all
the content into your own repository and continue working on it.

My understanding is that once you have the source you are free to do with it whatever you like, forever. But nothing I know of requires someone to provide access to the source code forever.
