So what exactly is your point?

> Our designers strive to create layouts that best fit the business and shouldn’t be limited by what framework we choose to use on the front-end.

Name any framework that doesn’t have an opinion about how to do something. A good developer is also one that sees a design and knows what tool fits it best.

>To use Bootstrap efficiently and understand it well you need to dedicate time to reading through the documentation, digging into the source code and figuring out how to customise it for your requirements.

Again, name a framework that requires 0 documentation reading time on the part of the user.

>Bootstrap doesn’t follow best practices or good semantics

This is an opinion best served by backing up what you feel good semantics or best practices are, because often times frameworks define what those best practices are.
