Yes as I've said they are different, but get used interchangeably. You can try your best to be precise in the conversations but there is too much incorrect momentum behind the wrong words sadly! It's like calling things fonts when you actually mean typeface. Or GPS when you actually mean GNSS.
I mean, one thing said was "Manhwa are very mobile friendly, the language is simple, and most notably they are colorful" which is true of "webtoons", not of "manhwa".
I don't agree that there's too much incorrect momentum behind the words; what I see in fan/piracy circles tends to be pretty clear about it.
