I'm going to continue releasing my software with a license that I deem appropriate.
For things I'm building only for myself or that I have no interest in building a community around, I couldn't give a shit what people do with it or if they contribute back. My efforts have nothing to do with them. I'm releasing it for the remote chance someone finds it useful, either commercially or personally. Partially because I've benefited from others doing the same thing.
I'm not anti-copyleft, but the only time I actually care to use something like the GPL is for projects that would be obviously beneficial to have community contributions. Things that require more effort than I can put in, or that needs diverse points of views.
I use permissive licenses not because I'm a pushover, but because I really don't care what you do with it.
