While there's parts about the GPL that I do like, I think it's a generally bad license. Above all, because it limits even FOSS projects from using your code, because it would basically force them to also use the GPL. A massive amount of FOSS projects are not GPL compatible.

I think it generally often just discourages the usage of your code. You have to be something utterly outstanding for most companies to consider even touching GPL code. At least with a more permissive license, some corporations will use your code and even if they don't all contribute, some will. e.g., my company uses a ton of FOSS code. We can only import code with certain licenses, obviously not GPL code. Me and my coworkers have personally made upstream contributions to improve these projects when we discover bugs or limitations. We do certainly also have some projects where we make internal only modifications, but most of those are changes that don't make sense to commit to the upstream (like adding compatibility with internal systems or adapting to our build system). Point being that the projects with permissive licenses will at least get some commercial contributions whereas most GPL software simply won't get anything (the likes of Linux is a rare case -- most GPL projects aren't worth it for companies).

As an aside, have you seen the LGPL? Depending on what you're developing, it can sometimes make more sense. Its use case is for libraries. It basically makes it so that if you change the library, you must open source the changes (like the GPL), but if you merely link the library, you don't need to do so. That can make it a bit more compatible with other people's projects while still having GPL-like tendencies.
