I mentioned the line breaks are by design. Roomba could be a hardware error or sensor noise. Text box not bringing up the keyboard it's hard to be sure whether that's a bug or intended. The auto thing not connecting could easily be hardware or deliberate. Letters from Amex might well be as specified by their processes. Webserver not running might have been deliberate maintenance.
Many of them could be software bugs, sure, but without actually figuring out what's going on and what the root cause is it's hard to tell.
Oh, I wasn't sure which direction the line break "certainly is" went in. But they have line breaks elsewhere in their post...
I would say failing to deal with hardware error that strongly is a bug. Keyboard I'm pretty sure is a bug, I've had plenty of situations where the keyboard code locks up and needs app restarts. Auto not being auto would be a weird thing to lie about, otherwise it's a bug. "Specified by their processes" a process is an algorithm, sending incorrect messages for $0 could be an algorithm bug or an implementation bug but either way it's a bug in the software, it's not doing that because someone decided it actually should do that. It said the webserver wasn't running but it was, that's a bug if they didn't have a exact unlucky timing.
