If you're moving sections around in a spreadsheet or a word processor, would it be more annoying if the copy/paste kept the formatting or stripped the formatting?
I think it depends on your workflow -- I'd tend to assume the receiving end has some formatting, and it would be best if the copied text was fit that formatting, rather than bringing formatting with it. Ultimately though it seems pretty arbitrary, I guess they just went with the default that benefits what they assumed would be the most popular workflow.
I dunno, we should all just use LaTeX to avoid these kinds of issues.
I don't doubt they want to. That's not the same as they should. I think actually you have three groups.
1. Most of the people on this thread that want default text.
2. People that carefully format documents.
3. Idiots.
The first two find copying the style over to be super annoying. Both have to remove it as a second step. The last don't know any better. That latter group is much larger than the first two.
