Form Inputs Browser Support Issue

It's hard to believe that this is the state of the web in 2015. I cannot but think that Google, Apple, Microsoft are deliberately trying to make web application difficult w.r.t mobile. 

Google owns Android & Chrome browser.

Apple owns iOS and Safari browser.

Microsoft owns Windows Phone (now Windows Mobile) & IE (and Edge).

Clearly they have a conflict of interest here. Each of them wants to push their own mobile-app infrastructure and have more mobile apps when compared to mobile web sites. Creating problems with Form Inputs is a simple way of discouraging web application development for mobile. 

Firefox is opensource and does not have the above constraint, but Chrome, IE, Safari seem to make the disadvantages subtle enough so that they are not really visible to the user (on mobile), but are a big deal for web developers.
