An open source client for iMessage is going to be used for fraud and spam. Before this, a device being blocked by Apple because it was used for fraud or spam would increase the cost of business for fraudsters and spammers. But now it's a matter of picking a new phone number. Of course Apple would try hard to stop this.

Is spam a good reason for Apple to keep their iMessage garden exclusive? SMS is also widely used for spam.

[mh8h]

I am not in the position to judge that. But reducing spam on iMessage is beneficial for Apple customers, and as a customer, I want Apple to be able to do that.

I’m in Asia, my phone number has been with me for almost a decade. I haven’t received spam in a blue bubble, only on SMS (green). Just want to give you a perspective in the other part of the world.

This are not just spam but most are sms phishing with links. We have poor, inadequate cyber laws, so we are glad Apple is doing its part sealing this off.

[StressedDev]

Yes - As an iPhone users, I am not really interested in getting more SPAM.

[MBCook]

Yes. It exists but (for me) is non-existent. I know others do get it.

I’ve never thought about it but that would be a huge black mark and could end up pushing a lot of people to WhatsApp/FaceBook Messenger/whatever.

This is exactly why Signal closed their source code: if you allow access to your network, you're only accepting spam. For their users' security, it's essential that they must guard access to their network as much as possible.

I feel the need to get a bit pedantic here. I'm not trying to pick a fight; I truly hope it helps clear up a few things.

Signal is open source. It's a fair argument that they make it difficult to use servers other than theirs, and we can't be sure exactly what they run server-side, but their code is possible to fork and all that. Their licensing is clear. Even the choice of AGPL is significant here: they must provide the source for exactly what they run on their server.

Network access is orthogonal to source availability/openness. Closing source as a means to limit access is security through obscurity. Not to say that it wouldn't work, but we certainly wouldn't expect the Signal Foundation to take this approach.

The most significant measure Signal uses to manage access to their network has to do with the phone number requirement. That's an intentional choice on their part (arguably controversial, but I don't have an opinion about it).

I've never received a spam message from another Signal user... is this common for you (or anyone)? I think in all the years I've used Signal I've only received less than 5 spammy "message requests" that are quite obvious/easy to decline because I don't already have their phone number in my contacts. I've always had to first ask someone "hey, can we use Signal?" so I'm already expecting legitimate message requests when they arrive.

Well no; spam yes, only spam no.
