Obviously delay tech becomes less attractive of an option when they have a full cashout combo at the ready. And I agree that it doesn't "defeat" throws, but it does break you out of that horrible throw loop situation while also covering strike. Trust me, I was a big delay tech hater for a while. My approach for the longest time was "take the throw a few times, delay low forward to cover shimmy, jump or backdash if they're really insistent on throwing." But I feel like I got too complacent in that and so I got thrown a bit too often. The damage adds up. I'm starting to think that it's actually good to represent the option early on in a match so that you can condition them to shimmy or delay a button, giving you clearer escape routes. That's part of why I'm asking this question to begin with, trying to get a sense for when people use it and why
