That line about it being dishonest got me. I always figured a bad seam was just a lazy shortcut, but framing it as dishonest hits different. It's like you're betting the next guy won't notice, or the paint will cover it. Saw a job last year where a rushed tape job cracked in six months. The time they "saved" got eaten up fixing it.
Read a thing last week that called sloppy seams 'stealing time from the future owner'. @riley_sullivan, your tape cracking example is spot on. It always comes back to bite you.
My old house had a corner seam in the living room that cracked every single winter for five years straight. The guy who flipped it clearly rushed the drywall, and we paid for it with constant spackle and touch-up paint. Calling it dishonest is so true, because it's a hidden problem you're passing on to someone else. That kind of work never actually saves time, it just moves the hassle down the line. It's like a bad debt that eventually comes due.
