I have read the terms of the Open Software License v. 3.0 (OSL-3.0) [1,2] and still can't figure out one thing.
In case I modify the source code, e.g. add custom support for SSO and some custom database, do I need to disclose the source code?
What does it mean to "communicate copies of " .." Derivative Works to the public"? I assume, providing access to customers falls under the definition of "communication".
How about the EE?
