Subscription/Service Fees

[SamBC]

I'm sorry if someone has already said this, or something similar, but
why can't people who want to distribute source, as they say, but keep a
financial gain from it, use conditions like:

1) On paying the license fee, you have access to the source code - you
may not distribute it in whole or in part, except illustrative excerpts
not more then [x] lines long

2) You may modify the source code as you wish, and distribute you
modifications only to other license holders.

3) On receiving a modified version of the source code, or any form of
instructions as to its modification, you may not redistribute them to
any unlicensed party, but may distribute freely to other license holders

Make the evalutaion entirely closed-source, if you wish, or include
pre-download or pre-execution agreement to a 30-day evaluation period
with some or all of the rights

And then not bother trying to claim it is Open Source, as it is clearly
not
