Also, these countries were once ruled by British.

I was adding commenting to the 4 countries you bolded. Just adding more input to your observation.
The bolded 4 Malaysia, singapore, India, and Bangladesh.

Actually British colonozition is really the cause of wide English language adaptation in these and other commonwealth countries.

You can check it out.

Google "why English is widely used /spoken in Bangladesh / india/ other commonwealth countries.

Because of the colonial master itself. All colonial master plundered its terroriries, but among the big power, Portugal, Dutch, Spanish, and British., British is the one that leave behind infrastructure, judicial, education, and so on. Had British did not come to Malaya after Dutch, we would have a very different history. A lot of our current systems are based on British system.

Dutch not so much on leaving these things.

And I in many parts of the world, Spanish is the worst. Besides plundering, they conducted genocide.

Because of what you said Bro. There are many languages. And English is sort of the common languages.

I was just adding to your comment that the origin of the unifying language which is English in the 4 countries are British empire.

Cheers.
