I don't think we need to disagree about this. What you say about the units is quite correct. I was just making the point that time is also a factor in relating an amount of data to the capacity of a channel. If you want to transmit a high res picture then you can use any 'bandwidth' you like - it may just take you a long time and that time is very relevant, sometimes.
'Bandwidth' is a catch-all expression that is used in the context of internet connections to indicate data capacity and it may not always be the whole story.
