This question already has an answer here:
I have identified a couple of open source projects on github.com that are not being kept up to date for many months. I have used them for personal use, and now want to make enhancements to them and start maintaining the code base and write sample clients that use these projects. I've sent
pull requests to the authors and also followed up with emails via their personal / technical website contact page, with no responses from either 1 of them.
I know that I can fork a project on github and be on my way. What I would like to know is
If I Fork an open source project and make improvements in the fork, will it or I offend the original authors? Meaning, could the original authors get upset down the line if my version of the project becomes popular and their version (the ones they are not maintaining or accepting pull requests actively) wanes in usage and popularity. A similar situation would be how Wordpress was forked from B2 and I think initially Mat Mullenweg and original B2 author had some difference of opinion / annoyances.
Are there any licensing issues and copyright issues that I should be aware of? At present, the
license.MDfor both Projects says Apache License Version 2.0, January 2004 http://www.apache.org/licenses/
