Why vB4 default theme was not a responsive design?

[webmastersun]

While more users liked to have a responsive design for vb4 default theme but vB team didn't work on it and used mobile style instead. What is the reason?

[Dragonsys]

This should probably be asked over on vbulletin.com

Responsive was not really a thing 6 years ago.

I agree with you but nowadays users using mobile devices are increasing, Google required it for better results on mobile search results and it could keeps web functions while mobile style is not.

Because it's a lot of work to make a real responsive theme.

Google does not require it, the Mobile Style included with vBulletin passes Google requirements just fine.

Also, we're talking about getting a full theme to be responsive. Not a flimsy paper mache white & blue theme offered by default by vbulletin.

Lats week actually, but the reason I say Google does not require it, is because the mobile style works

I am aware what the discussion is here, but I'm saying that the current mobile style works for Google's requirements, even though it is rather ugly and not fully functional.

If you are not a SEO specialist then your answer is quite true but it is total wrong if you know more knowledge about SEO to distinguish between mobile style and responsive design on SEO aspect.

Of course you use mobile style, you can pass Google's requirements here

But on other aspects, responsive theme is always better.

Not disagreeing with you on this, but you only stated that Google required responsive for Mobile, and this is what I responded to.
I have also agreed that the mobile style is not the best, but at the time is was a good solution. Responsive wasn't even a thing back when vb4 was originally written, and other things have been much higher on the radar then making it responsive when that actually came about.

And now with vb5 being out, I highly doubt it will ever change for vb4.
