Most people don't care to fix Wikipedia articles either. But I really appreciate the people who do. Turning off the discussions behind those pages would be a terrible disservice to the people who do contribute.
Likewise, turning off issues makes it much more difficult for us contributors. You can't search issues to see who's working on what, get advice or guidance from the community for nontrivial fixes, and otherwise have high-level conversations before even touching the code.
For those who just open issues, it's not always about laziness. Sometimes, you just don't have that much invested in a particular project. Personally, I still open issues to projects I use infrequently. I can't justify diving deep into a new codebase, reading their style guide, debugging, fixing the broken code, double-checking my fix, adding the proper tests, and documenting it in every case, but I'd be happy to spend the 5 min to search the issues and post a new one if necessary.

Please don't do this.
