I imagine people who care about this sort of thing are more likely to report it. And people who care about this sort of thing are also more likely to be early adopters and go through the effort of switching to Wayland.
The way to get a more random sample is not something I want (built-in, automatic telemetry by default). So I’m fine with having skewed data for something like this.
I have tried KDE connect, and it never works when I need it to. I just send it to myself on Signal. It’s the easiest, most non-bullremoved way.
