Open source, closed source, and the value of code

Robert, I appreciate your thorough thoughts on this. You covered a lot
of ground, and you seem to have your mind well made up on open source
license options so I won't try to convince you of anything here, just
providing some links and background info for others who may share
questions along these lines:
> First : no. The allegation about hypercard forcing the open source
> path on all usage is not true.
I don't think anyone was claiming that. HyperCard was very clearly
released under proprietary license with specific terms and conditions.
Bill Atkinson's commented I quoted seemed more to reflect a good
appreciate for open process and for sharing in general, but in that
video he expressed so opinions about GPL or any other open source

Originally HyperCard was given away for free with every Mac.
Indeed, once it became a product under Claris it proved difficult for it
to sustain itself economically.
FWIW, LC has experimented with a wide range of price points over the
years, including many that match price points suggested in recent
related threads here. If they had produced the sort of results hoped
for we wouldn't be having this conversation today.

According to the authors of the GPL, copyright of data output by a
program is different and separate from copyright of code:

That is a distinguishing feature of the GPL and other related licenses.
And as Matt pointed out earlier this morning, there are many other
open source licenses as well, such as the MIT/X11 license he's using,
which differ in terms of downstream responsibilities.
Matt chose to obtain an Indy license so he can use MIT/X11 for the work
he produces from it.
Choosing the GPL-governed Community Edition means choosing GPL.
We have many options to choose from, so only those who choose the
GPL-governed edition are obliged to the terms they've chosen.

Trademarks are very different from copyright. They require separate
filing, and have different enforcement requirements as well.
Regarding copyright of media incidental to a work, for the distinction
between code and output see the GPL FAQ link above.

If those elements are code there may be a conflict, or not, if the
license of those elements allows it and is compatible with the GPL.
There are several questions in the FAQ I linked to above which cover a
wide range of circumstances relating to such circumstances.

It is true that the US government has allowed a single corporate to
revise its copyright law. Whether allowing such a practice is useful
for the general public has been the subject of much debate both in the
US and abroad, and is - thankfully - beyond the scope of this list. :)
> A largest part of our economy will now more and more rely on these
Yes, the "founding fathers" of the United States drafted the
Constitution with explicit provisions for providing for protection of
copyrights because they believed intellectual property was valuable.
The Berne Convention which makes the GPL and all other distribution
agreements possible has been signed by more than two-thirds of the
Protecting copyright is generally considered valuable so that creators
of original works have the right to choose the terms of the distribution
of those works. Whether they choose an open source license or a
proprietary one is up to them.

Using the TIOBE index ( <http://www.tiobe.com/tiobe_index>) as a guide,
we can look at several there:
Java: mixed somewhat like LC, with a proprietary version and a
C, C++: my understanding is these are open specifications; tools
implementing those specifications vary, but among the most
popular compilers is GCC, the Gnu C Compiler from the same
folks who wrote the GPL.
Python, PHP: both open source, but under their own unique terms.
Their licenses are generally considered more "permissive" than
GPL in that they have no "copyleft" provisions (downstream
requirements for adhering to the same level of openness they
offer), but it's worth noting that the Wordpress, Drupal, and
Joomla projects are among the world's most popular systems
built on PHP and all three explicitly define all themes,
modules, and other add-ons as "derivative works" per the GPL
and require GPL for such works:
VB.net: Historically proprietary, with a subset recently release as
open source under MIT license.
Delphi: Proprietary, though a GPL-governed variant is available
through the Lazarus project.
Ruby: Open source under BDSL
Swift: Mostly open source now (language only, I don't believe any of
the Cocoa framework needed for effective use of it on iOS is
included in that) under Apache v2 license.
R: Dual-licensed under MIT or GPLv2
Groovy: Like most projects stewarded under Apache, uses Apache v2
Scratch: dual-licensed under MIT or GPLv2.
There are a lot more listed there, too many to cover here but each has
its own license info that can be found if interested.
For a broad view of FOSS license adoption this chart has a breakdown
showing license popularity by project count:
While MIT and Apache are growing in popularity, GPL's family of licenses
(v2, v3, AGPL and LGPL) continue to dominate.
