That's a legitimate security benefit, fair enough.

I do get actual businesses sending me SMS notifications with links, and they aren't in my contacts either, but it's a valid decision for Apple to have made in terms of weighing off reducing scams vs creating inconvenience when genuine messages aren't clickable.

On a personal level I'm happy for everything to be clickable on my phone, because I trust myself to be cautious about scams and think carefully about the legitimacy of a message before I click anything.
