Since good kashruth puts bad kashruth out of business (it doesn’t cost all that much more to do kosher properly, and you get a bigger market), of course the standards are rising. Why make imitation hametz out of matza crumbs when you can make it out of potato starch, probably for the same or less cost, and increase your market share.
