I was confused they didn't think of this either, but the language in the license is very clear. I see no way it cannot be infringing - the only way you can be restricted from redistributing GPLv3'd source is if you publish it incorrectly.

That's ignoring the variety of other OSS licenses used for software in their repositories, many of which have similar (or even broader) redistribution rights.

Relevant GPLv3 language:

Section 4. Conveying Verbatim Copies.

"You may convey verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice; keep intact all notices stating that this License and any non-permissive terms added in accord with section 7 apply to the code; keep intact all notices of the absence of any warranty; and give all recipients a copy of this License along with the Program."


Section 5. Conveying Modified Source Versions.

"You may convey a work based on the Program, or the modifications to produce it from the Program, in the form of source code under the terms of section 4, provided that you also meet all of these conditions:
a) The work must carry prominent notices stating that you modified it, and giving a relevant date.
b) The work must carry prominent notices stating that it is released under this License and any conditions added under section 7. This requirement modifies the requirement in section 4 to “keep intact all notices”.
c) You must license the entire work, as a whole, under this License to anyone who comes into possession of a copy. This License will therefore apply, along with any applicable section 7 additional terms, to the whole of the work, and all its parts, regardless of how they are packaged. This License gives no permission to license the work in any other way, but it does not invalidate such permission if you have separately received it.
d) If the work has interactive user interfaces, each must display Appropriate Legal Notices; however, if the Program has interactive interfaces that do not display Appropriate Legal Notices, your work need not make them do so."

I find it interesting that even the conservancy can't really say whether or not it's OK legally definitively. Here's hoping someone still takes them to court over this, wins, and sets precedence that it's a violation of the GPL (extremely unlikely, but a guy can dream)

I remember people talking about potential scenarios very similar to this when Red Hat was acquired. They were right.

Yeah, it kinda does. Idk what they're thinking, lol

From TFA:

Some commentators are pointing out that it's possible to sign up for a free Red Hat Developer account, and obtain the source code legitimately that way. This is perfectly true, but the problem is that the license agreement that you have to sign to get that account prevents you from redistributing the software.

So although the downstream distros could still get hold of the software source code, they can't actually use it. In principle, if they make substantial modifications, they can share those, but the whole raison d'être of RHEL-compatible distros is to avoid major changes and so retain "bug-for-bug compatibility."

Of course, they could take a "publish and be damned" attitude and do it anyway. At best, the likely result is immediate cancellation of their subscription and account. That could work but will result in a cat-and-mouse game: downstream distributors continually opening new free developer accounts, and the Hat potentially retaliating by blueprinting downloads and stomping on violators' accounts. It would not be a sustainable model.

At worst, though, they could face potentially getting sued into oblivion.

ETA the full context.

Idk, I don't think they're trying to kill downstreams. IMHO, they're just cleaning things up. Why should the RHEL source be in the CentOS repos?
