I try not to think about the collective time and frustration lost to companies wanting their native apps to be "on brand" and cross-platform consistent rather than native. A bunch of extra work to make it that way. A bunch of extra work to maintain it, any place dumb "look and feel" shit like specially-animated buttons or whatever made it fragile. Then on the other side, 99% of the time it's worse to use than if they'd at least
mostly stuck with native widgets, so wastes time and causes frustration among users, and then there's the special case of that for accessibility, which is often a true shit-show.
All because the marketing suite can't stand not getting their fingers in something. I want to see the fucking study that says having the buttons on iOS the same shape as the ones on the website adds any number of dollars to the bottom line. C'mon, this is important enough to spend a bunch of money on, slow development, and also make UX worse, must have a good reason for it, right? Surely it's not just an exec who's never done the actual job pushing things for vanity purposes, or a variety of roles padding their portfolios, or needing to market this to toddler-like C-suiters inside the company on some damn powerpoint, right? LOL.
