It's why SMS still exists too. It's from an era where everyone just used open standards instead of trying to create their own thing for money. Big tech conglomerates like we have now didn't exist. The state of the tech industry and it's proprietary standards is absolutely fucked.

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

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.

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)
