Google is trying to kill SMS. My new android by default has sms disabled, defaulting to RCS with "try sending sms instead if rcs fails to send" option being off by default, which makes no sense from user perspective

RCS is actually a huge improvement over SMS, as it is fully encrypted. One of the few times I've ever approved of something Google did...

If only it was an open standard...

[-] Bman915@lemmy.world 9 points 8 months ago

It... is? It's an open standard that anyone can use and implement. The main provider is Google and there has been a huge push from them to get Apple to adopt, which they mostly have. It's not 'owned' by any company. It's predominantly serviced by Google, but is in fact an open standard. Google and others have their own format which is how they and their apps interpret and interact with each other, but it is an open standard. There are some backend and requirements for it which stops most from setting it up and implementing off the shelf and just going with Google, but you absolutely could use and make your own format with the standard.

Yep, main reason it's associated with Google because they bought a company (Jibe Mobile) making one of the main backend service offerings and offered cloud hosting of it, so providers just went with that rather than rolling out their own software.

Also with Apple ignoring it in favour of iMessage, Google was the only one supporting it on handsets. Google client + Google backend = people think it's Google's iMessage competitor.

which makes no sense from user perspective

I'd say it does have some merit from a security perspective though.

I agree it should be something that's at least more clear for users to enable/disable on setup, but I personally don't think having it enabled by default is ideal, considering how insecure SMS is.

...but I can literally send infected files thru RCS to my grandma.

[-] ArchRecord@lemm.ee 5 points 8 months ago

True, as is the case with almost any messaging service. But the benefits of RCS do include:

  • Not having a government/telecom company be capable of snooping on your messages
  • Branded messages that clearly distinguish real companies from fake ones, which can prevent an untold number of scams as it becomes more commonplace
  • Uses more modern protocols instead of still being capable of sending over old, insecure ones like 2G.

It's purely an improvement over SMS in terms of security and privacy, and personally, I don't think users should be defaulted into having their phone downgrade to insecure protocols. It should always be an opt-in decision they have to make. (although they could definitely make it clearer that someone could enable it if their messages are failing to send with RCS)
