Why doesn’t Slack write an actual Mac app in Swift? For small companies with limited resources, I understand the attraction of “cross platform,” but it would seem that performance and uasability would be vastly improved by writing actual native applications — especially for a billion dollar company that can afford to do it and especially since Slack is one of those apps that is constantly open and performance and efficiency have a real benefit.

They've cornered the market and don't have to care anymore.

A lot of Slack's audience is captive - employees, contributors to open source projects that chose Slack as their social outlet, etc.

The only way this will change is if Apple starts using more "stick" approaches. Marzipan and whatever other technologies they're working on are the "carrot".

Amen. “Cross-platform UI” has always meant “doesn’t work well.”

Yeah at this point they are basically jerks for not building something better. The reality is they dont have to care.
