I didn't mix those things up, I just used them in the same sentence.
They are two aspects of "ownership" and appear to offer conflicting
messages, which is a concern to some users.

Yes, are they open source licences?

If, as you say, the licence is unclear then whether-or-not it is an open
source licence must also be unclear.

The copyright holders can change the licence in future as they see fit,
as we've witnessed on other formerly open source projects.

Since the licence is unclear now and the future is subject to change, I
think its safe to say that those projects are fairly unsafe for open
source users.

I'm sure the various other Telco companies out there don't want to hear
that they are using software that NTT might decide in the future to
contest as to whether it was open source or not. Nothing against NTT,
though the principle is clear and effects everything on pgfoundry.

That puts a fairly large hole in recommending that people visit
pgFoundry. That either needs to fixed or users will no longer be able to
trust PgFoundry.
