Why does habr still have a mobile version of m.habr?

Question

Habr

Why does Habr still have a mobile version, and not an adaptive one?

Answer 1

Haven't you noticed yet that most of the services on this planet use mobile and desktop versions instead of one responsive one? Over the question "Why" I propose to think for yourself.

Answer 2

When adaptive on a mobile phone, extra resources will be loaded, extra blocks will be displayed, etc.

Answer 3

Because instead of adaptive fonts, it is useful to develop separate functionality in general. Since on a computer I navigate with a mouse or hotkeys, and on a phone with a touchpad.
Setting up a universal adaptive site means constantly making compromises to the detriment of functionality, convenience (and traffic is not the last moment).
