Unfortunately, you violated the law slightly by asking a question!

Cunningham’s Law states “the best way to get the right answer on the internet is not to ask a question; it’s to post the wrong answer.”

Damn, I’m glad you made this comment as that is an amazing gif!

I’m hoping RCS’ burgeoning ubiquity on Android breaks some of the walls down in Europe, at least.

Be careful with the cable tension barrel adjuster. As you turn it, watch the brake caliper: is there is any movement, stop turning the caliper and back off.

It should only be used to remove slack in the cable on installation - it shouldn’t be used to adjust the brakes.

This is because a disc brake caliper only has a few mm of travel. So if use of the barrel adjuster “removes” 1mm of that travel, you end up with far less modulation available.

Yup, hard agree with you on that last point.

That’s an interesting example, but note that in Europe, at least, WhatsApp is king. I only mention it because the walled-garden approach Apple favours isn’t necessarily a guaranteed outcome, and third-party apps can happily become the norm among non-tech people.
