The most important info is at the bottom of the screen. I also believe you can turn this feature off if you prefer plain text

But who’s going to go to that effort on their slab of glass?

Those who would like to make extra sure their data stays private. On an unrelated note, what kinds of data could be considered confidential in said log?

I disagree. The logs typically do not fit on the screen in text form, especially on low resolutions (like if the system has to fall back on an alternative graphics mode, which tends to happen more frequently in the event of a crash). Granted, a website is not the best possible solution and has the risk of leaking data but at least it is “a” solution. The data is encoded sure, but not in an obfuscated way. If you wanted, you could decode it with other means (for example a dedicated app that scans it).
