Kind of a mixed bag.
Hopefully they can dodge RCS too, because it's a poor solution. Worse, Apple's implementation of RCS doesn't include E2E encryption.
Edit: RCS limits attaments to 100mb! What the hell, why? I can, today, send 100mb over SMS/MMS, on Verizon, to other Verizon phones. RCS would be a step backward.
I don't really care about iMessage, Android is my primary device, and SMS sucks, and most people use SMS because Android, and I prefer to use other apps (especially on my iOS devices).
IMessage has its own insecurities, despite what people think. There's a recent publication about it while it uses AES to encrypt the message, the encrypted message and the AES key are packaged together with the RSA key...which never changes. So if you get someone's RSA key, you can decrypt all their messages, old ones, new ones, ALL of them.
So if they can dodge it, this keeps the pressure toward third-party apps with proper encryption, that isn't tied to your IMEI, Google or Apple accounts.
And this is what governments fear the most - they peoe will use apps like Signal, where not even the metadata is easily accessible or useful even if you could access it.
Here's just one well written example of what's wrong with RCS: https://www.reddit.com/r/UniversalProfile/comments/11b6fyd/ugh_rcs_really_does_stink/
The text of that post:
A 100MB file transfer over MMS? I'm not saying you're lying, but recognize that is highly abnormal and most carriers aren't going to support anything near that high. 100MB would be a huge upgrade for most people over MMS.
I have no idea what carrier this user is with and I agree that sounds absurd. Photos and videos are automatically downgraded before being delivered. The file size limit is typically below 5MB. Videos are like 480p and photos are 720p. I hate sending photos through MMS and would rather use data with a different messaging app if RCS isnt available.
He said it's Verizon.
Ah I missed that. Thanks.
In any case, I think this user is confused. See here: https://www.verizon.com/support/knowledge-base-14641/
I think this is where the confusion stemmed from.
Makes sense, thanks for clearing that up!
