> macOS Messages (aka iMessage) has been rendering text chat using HTML views for years, and it doesn't use gobs of memory.

Keep in mind that the OS and the hardware it runs on comes from the same company that does iMessages. You shouldn't discount the amount of control that brings.

Contrast that to people who have to work with different OS platforms and hardware specifications.

Adium did exactly the same thing - rendering chat contents using HTML. It also didn’t use gobs of memory.

The hard work of optimisation has been done by apple, any app can embed a web view for content and take advantage of the optimisations in the system html renderer.
