Because the conventions that are considered “standard” evolve over time to match the most common usage. Non-western English is probably already the most common English, due to India alone. Those speaking patterns have been relatively isolated so far, but online media brings it into the mainstream. My main claim is that it will take over the present “standard” usage, because of the sheer quantity (but not in an alarmist xenophobic way, lol).

Some examples that have become normalized for me personally, I think due to working with lots of international folks in tech:

- “i have a doubt” instead of “i have a question”

- “i will not claim X” instead of “i would not claim X” or “i don’t claim X”

- “this is not as X as compared with Y” instead of “this is not as X as Y” or “this is not X compared with Y”

- "it will anyways be fun" instead of "anyways, it will be fun"

I’m not sure if these are broad patterns, or just peculiarities of the specific crowd i hang with. And I don’t think these are standard usages yet, but I’ve become familiar enough that I say these sometimes, despite intuitively feeling that they are wrong.

Edit: i think most of the phrases i have adopted are from Indian English, but unsure.
