As I am nearing a release using CI3, I took the time to go through the thread and the posts from Derk, WanWizard, and skunkbad cleared everything up.

1. OSL only applies to files with the OSL header in them (stock core files).

2. AFL only applies to files with the AFL header in them (stock config files).

3. You DO NOT have to give out your "application" source. Files you create do not have the OSL license header (unless you put it there), they are yours to license how you want to.

4. You ARE REQUIRED to release modifications to "system" files with the OSL header, as the license is reciprocal.

5. You DO NOT have to put a link on your site saying powered by CI.

You are not obligated to actively point your individual website visitors anywhere; OSL 3.0 has no advertising clause. Attribution is only required in the source and other locations that the licensor clearly defines as such a notice. Please see the Agency example in this week’s post outlining examples of OSL 3.0 compliance.

6. You DO NOT have to provide site visitors with the stock CI source code. It is already publicly available.

As Derek already mentioned, the fact that the source code to the Original Work is already publicly available (published by Ellislab) is enough.

If your app doesn't use modified core files nothing really changes. All the OSL license is saying is: "we gave you stock CI for free. If you modify the files we gave you, you have to reciprocate and provide your modifications for free."

Using the files does not constitute a derivative, only changing them does. If you overload methods vs editing them directly (as you should be doing anyway) you are indeed in the clear, and nothing changes vs. 2.x (for 99% of us).

Sounds like this was blown way out of proportion.
