Well said. Thank you.

Can you tell us more about this? I am not at all clear what your customer
is worried about, and thus I am unclear about the motivation behind terms.

I agree that this is a social problem suffered by computer users. OSI has
previously rejected licenses that attempted to use their terms to remedy
social issues beyond sharing software freely. It's out of scope of OSI's
mission, *and *OSI's stated mission for Open Source software.
The previously proposed licenses with similar terms have in general been
rejected because of the increase in legal load for the *passive user.* The
person who doesn't create derivative works or redistribute, but just runs
the program. They shouldn't have to read the license just to run the
The CAL breaks that. Passive users of software under the CAL would face
real legal questions regarding data release in conjunction with the terms,
which they could not handle adequately without counsel. This, IMO, is an
unacceptable burden on the user.
It's really difficult for anyone not an attorney to parse the terms of this
license and arrive at what their obligation is, figure out where ownership
interests and possessive interests are involved, etc. There is nothing
approaching plain language that states the obligation. And I suspect there
is some uncertainty even regarding attorney's opinions.

Blockchain requires use of one-way functions, as does any algorithm that
supports a verifiable public signature. The input to such functions is
necessarily irretrievable and requires some sort of secret, usually in the
form of a private key. Private keys (usually in the "wallet") must
or the basis of trust in the system is destroyed. So, be sure your license
doesn't require their disclosure. It seems to me that under the present
terms it might do so.

It's not the same action. Our other approved licenses require conveyance of
the source code only. And in a meaningful way only from *developers *who
create derivative works. Here you add data to the terms, which none of our
other licenses require, and you require it of *users *of the program who
are not developers. Vastly increasing the legal burden of users.
The terms do include use restrictions: by your own statement they restrict
the user from denying their customers access to their data without a
continued payment. You may consider this socially beneficial, but it's
pretty clearly a use restriction. I don't see how this is different from
the previously rejected licenses with other social goals implemented as use

Yes. IMO, it's over-reaching.
The insight is that, increasingly, the data and the code are needed

This is proposing that the data previously used for an arbitrary run of the
program is essential to use the program at all. I can see this for data
which defines fundamental characteristics of the world around us, for
example a book of physical constants of the universe. But you are extending
this to transactional data of a specific market, and denying that the
program could be used in an alternate market. It's not logical.

Yes, but a lack of specific market data doesn't actually prevent the
execution of the code, as a key in a "trusted" boot system would.
The CAL recognizes that user freedom also includes the provision of the

Thus, someone who wishes to have the freedom to sequester the data of their
customer users *must be deprived of that freedom. *We restrict people from
keeping derivative works private in some cases, because we're the Open
Source Initiative. But now, we are going to restrict people from keeping
data private too, because we're now the Open Source and People's Data
It's over-reach. Sorry.
