You can circumnavigate it.

Just use revanced to patch sync to use a personal API key.

Or compile an open source client like infinity to use your own api key. It’s free and you can continue to use the apps.

It doesn’t screw anyone over because at least for now, Reddit gives free api keys to users (with limitations most users wouldn’t exceed) - they can’t even tell what the app actually is.

But there’s no reason to believe they won’t eventually remove free api access for users as well. You can do what you want, but it’s a sinking ship hoping to use third party apps long term.

Especially since the apps are no longer being developed, if reddit makes a change the app can’t cope with, bam. done. It’ll work for now though.

Personally for me, it’s easier to just cut that chord now.
