Maybe he’s tired of supporting them. Maybe he doesn’t use those anymore so it doesn’t make sense for him to support them. You can fork them if you like. You could be the next maintainer as it is open source.
It takes time to support repos. Supporting repos is work. I know because I support a bunch. It is often a thankless job. People always want something, but often don’t want to put in effort to contribute (even if it’s just a simple donation). People don’t like to read the documentation and love to ask a question you’ve documented and answered hundreds of times. People don’t like to follow instructions you give them to get your support.
With that said, there are people who do contribute. And there are those who occasionally give thanks (sometimes verbally and sometimes with donations and sometimes with pull requests). Those are the people that usually give repo maintainers the motivation to keep supporting the project.
In short, sometimes it can just get tiring. And if you’ve moved on from your project (you don’t even use it yourself anymore), it might not make sense to keep supporting it. Only tito can answer exactly why. But I imagine he either doesn’t use them anymore and/or is tired of supporting so many repos.
