tankerkiller125 I'm not a fan of big companies using open source software but not contributing back when they make changes.
GPL or AGPL may be good for app or if you're building ecosystem (like WordPress), but this is terrible license for libraries or extensions, since it may affect the whole app. I'm not a big company, but I'm avoiding dependencies licensed under GPL (not mention AGPL) just to save myself problems with licenses compatibility.
There is also a reason why most of PHP/JS frameworks and libraries are using permissive licenses like MIT or BSD - cutting of business does no help the project. Proprietary apps will just use different library or in-house solution (which is probably worse solution for everyone), so you're loosing potential source of valuable feedback and PRs.
