Good news, you can grab the source code and host it yourself on a less troubling domain:

https://git.j3s.sh/vore

It's under the NON-VIOLENT PUBLIC LICENSE v5, which is probably not open source, but should be fine for personal use if you're not an arms dealer or prison warden.

There's more RSS readers than you can count. No need to pick a proprietary one with a sketchy license when there are tons of great open-source options.
