Re: I'm with Ms. Swift
"I don't recall Spotify and their ilk being particularly generous with the ol' moolah either"
I don't recall Spotify having a huge bond issue in the US so they could pay their shareholders dividends without having to pay tax on the cash which was sitting outside the US (see also Naughtyhorse's post).
I don't recall Spotify being invited before a House committee in the US and being asked where they were resident for tax purposes. I do recall that happening to Apple, and I do recall that they answered that they weren't resident anywhere for tax purposes.
