so if i build an app that enables endusers to upload videos from their phones to youtube and then offers a labeling system so that ice-related (or other) activities can be interlinked and searched/discovered/traversed i am suddenly engaging in proscribed software development? how far down does this slope go???

it goes as far as the king or his loyal enablers think it needs to go. the slope is very short, actually, because the moment you do that you'll have a target on your back and might receive a visit from a federal law enforcement agency.

to go further: let’s say i don’t even define a purpose for the app but just leave it open to users to define their metadata labeling scheme and all the app does is index the videos labeled in a common way. perhaps endusers agree on redit or on some wiki how they will label posts. the app just traverses the labeling scheme and provides some basic viewing and searching locally; without a server involved beyond youtube. i’m just wondering whether this new situation essentially criminalizes metadata.

The drone strikes app tried to use the "metadata" excuse. https://tech.yahoo.com/general/articles/apple-finally-approv...

The underlying principle is not complicated; Apple can and will ban any app they don't like.

The judge will say "you knew what you were doing" same as they do for all the torrent hosts.

criminalization of aggregation

is there some point of app abstraction where i can claim section 230 protection?

When users create the lists and you don’t moderate them (outside of illegal content and “profanity”. But “profanity” is similar to the slippery slope of a “targeted group”.

S230 allows for any amount of moderation. Providers of interactive computer services are not liable for user-uploaded content.

ok so , in theory, “Mark” (the author of the original app in question in the original post) could change some of the verbiage around his app and resubmit claiming 230?

Section 230 doesn't protect you from Apple or Google.

This was written re: IP law, but applies to your comment as well.

thanks for sharing! someone had explained to me the concept of “color of money” in payment systems years back and this matches up well.

If they can’t remove your app from the store, they will use advertisers to coerce you to whatever changes they are after, if that’s not the case, they will force you to sell your app.

or they can convince the payment processors to refuse to do business with you
