I created an iPhone app called MyHumans that takes the opposite approach with a whitelist using your phone contacts. Other callers are sent to voicemail without ringing your phone. It has an easy to access switch where you can temporarily disable any blocking for a time period, like an hour, if you're expecting a one-off call from a recruiter or whatever.
It works really well for me. Spammers rarely bother leaving a voicemail and legitimate businesses leave a voicemail that I can follow-up on later.
If a customer signs up and setups payment for the service outside the app, then Apple doesn't take a cut. That's why you can't buy books in the Audible iOS app, or subscribe to Netflix via the iOS app. But you can login and watch/listen to content you've already bought or subscribed to.
Here we have the FBI telling us if we don't want to be spied on by TV manufacturers with cameras to just use some black tape :facepalm:

If you give over control to cryptocurrency by sending your cryptocurrency to some entity that exists outside of a trust-less blockchain system (centralized exchange or otherwise) then that entity can do whatever they want with it (technically-speaking), and you are essentially then reverting back to and relying on non-blockchain technologies at that point (The exchange was probably just a typical web app built with some common web framework and RDBMS). Obviously, ponzi schemes are possible without blockchain technologies and in a purely blockchain world, because of the transparency of transactions, it would be very difficult to pull off without having willing-participants.
There is a separate discussion to be had of how to use blockchain with "legacy" centralized systems and how to make it user-friendly for non-experts, but it's not an actual problem with blockchain technologies itself, but more of a second-order problem.
The main thing being discussed was digital assets, so if you have 2 pure digital assets that are compatible with smart contracts, you can exchange without any trust and it prevents things like ponzi schemes. Government money, like in the example, really is more of a "legacy" centralized system, which allows for this. That's partly why you are seeing entities like Coinbase try to create "stable" cryptocurrencies [1] that try to mirror the value of government money.
Solving the trust issue is what an immutable ledger and consensus algorithm is all about.
Without a way to agree on who owns what and a way to enforce that then there is no way to have digital ownership or freedom without an army of lawyers and law enforcement, or trust.
You probably already have ownership of digital assets without blockchain: it’s called a bank account, equities, bonds, and maybe a title or deed to a car or home. But that ownership is all enforced by an entire system of laws, attorneys, law enforcement, and other fallible human beings. If you remove the reliance on that system and fallible human beings, you then begin to enable a greater amount of ownership and freedom than previously possible.
Blockchain is most useful in situations where there is a lack of trust between parties. Seems like a lot of people on HN distrust PayPal because of being bitten by frozen accounts or having their earned money revoked. That’s why money is a good use case for blockchain.
Voting is another - maybe you don’t trust that your vote for the radical will be counted correctly.
Smart contracts are another. If the other party decides they don’t like the current state of affairs (they are losing) then it’s much easier and less expensive to have the contract auto-enforced than using a army of law enforcement and lawyers.
If HSBC is actually using this to create an immutable record of transactions that ensures integrity of the logs then it would be a good use case, but I have my doubts.
Both stores having the same exact revenue share may just be a consequence of there being a duopoly, or it may be more nefarious where active collusion has occurred between the two. Remember when Apple and Google got caught a few years back colluding against labor? https://www.cnet.com/news/apple-google-others-settle-anti-po...
Now, yes, Android does allow you to download apps outside the Play Store, but not by default. Microsoft was able to make a similar argument with Internet Explorer and Windows with it's monopoly cases. If you are one of a few large powerhouses like Fortnight or Tinder, you may be able take advantage of being able to bypass Play Store.

It's almost a tragedy of the commons where there is a generic trademark that isn't protected, or maybe in the opposite case where everyone colludes to dilute the generic trademark to increase profit margins. Like using "blueberries" that aren't real blueberries but just made up of sugar and some artificial ingredients.
Sounds like Stockpile - They sell gift cards for stocks.
I've tested out the "silence unknown callers" feature in the iOS 13 beta and it works very much in a similar way. "Unknown callers" seems to be any call that isn't in your recent calls or in your contacts.
When I made MyHumans (just launched in the last month), I knew there was a risk of something like this appearing in iOS 13, but I'll be adding some more features.
