Isn’t that the same one?

It is absolutely a people problem just as much as it's an infrastructure problem.

We call them multi-use path (MUP) here. It has a yellow line painted straight down the middle, and people, whether they're walking, running, riding a bike, rollerblading, are expected to stick to their side of the path.

I've lost count on the amount of people on the MUPs wearing something that removes their situational awareness, be it ANC earbuds, or over the ear headphones, etc...

So why did I bring up the lane division? Because on top of people choosing to completely occlude themselves from their surroundings, a subset of them also like to walk/run/etc... abreast, completely taking up the path on both sides. So if you come up behind them, and they're taking up the whole path, you can't get around them without ringing a bell, or asking them. And if they're very engrossed in their conversation, or they're wearing headphones, it's even harder...

The point of a MUP is to share the path. It doesn't give a right for any kind of users to practically occupy the path, and then act very offended when you finally got their attention to get around them.

It has got to the point that I rather bike down the MUPs in the rain, because these users with no etiquette aren't dedicated enough to be out there in the rain.

The root problem is forcing or allowing cyclists and pedestrians to use the same spaces. Traffic must be segregated by speed.

There's a third use: alerting pedestrians who are in dedicated cycle lanes and letting them know they need to get out of the way. Not because you'd mow them down otherwise but because someone else might.

Separation of traffic into cars, bikes and legs is great, whenever possible. Just as a car shouldn't mow down a pedestrian in the road, the bike shouldn't mow down the pedestrian in a cycle lane. Doesn't mean the pedestrian shouldn't get out of the way when they're in the wrong lane.
