It’s cheaper to build multiple native applications than one responsive web app
"You want mobile notifications? Sure, but not on mobile Safari."<p>You can do this with PhoneGap.<p>"Multiple line ellipsis? Sure, but only on webkit."<p>Okay, yeah, this sucks.<p>"Consistent rendering size across browsers? Just fuck off."<p>This is probably your fault.<p>"We fix a layout bug on Safari and break something on Edge."<p>This is probably your fault.<p>"We change font size on Chrome and now all you can see on Firefox is the letter F."<p>This is probably your fault.<p>"How about hiding the address bar or controlling swipes from the left edge of the screen? Don’t be stupid."<p>Stop trying to make the browser not a browser. Users hate when you hijack expected behavior. (See: Imgur.)<p>"Oh, and don’t get me started on all these new custom mobile keyboards you can use and how autocomplete can fuck with your input box events."<p>You can disable autocomplete. Did you mean predictive word suggestions?<p>TL;DR: "We tried to make a responsive web app act like a native app and it didn't work because <i>it doesn't work</i>, and that makes me a grumpy goose."
