You're not wrong, but the License used is critical here.

If the code is indeed Open Source, with an OSS license, then you can use it as-is, or just learn from it and write-your-own. You might even fold it as-is into your app. Keep the code, but remove the dependence.

Free Software on the other hand is a different animal. The GPL et al is viral. Doing any of the above with GPL software has consequences. Even learning and rewriting is risky- the rewrite better be more than just variable name changes.

If you're old school, and you want to share on a "do what you like, I'm not turning this into my day job" basis, where you want folk to actually benefit, yhen I recommend an OSS license over a Free license.

On the other hand if your target audience are other Free developers, then a Free license makes complete sense. And if you plan to commercialize your project down the road an aggressive Free license (like say AGPL) is a good choice.

Ultimately your choice of license should match your goals.
