Re: Oh it's worse than that.
The following comes directly from the Google terms of service .. . .
Some years back I was involved with the development and marketing of a couple of small businesses.
I sat down with the people involved and went over Google, LinkedIn and Facebook terms. Surprisingly, FB was the best of them. Google and LI claimed a perpetual license to use any material you supplied for their purposes as you quoted, and stated elsewhere that even if you deleted the content from their servers they could retain a copy and use that content for their purposes. FB, on the other hand, took license to modify for the purpose of displaying (eg you took a panoramic photo they could clip it for a thumbnail), and if you deleted it you understood that copies may remain on backup media for a time (until the backups were wiped). I don't defend FB, but at that stage they had by far the better policy.
I strongly recommended to these businesses that they did NOT willingly upload their logo, tag-lines or other IP data to Google or LI - if they did they lost the ownership rights to them and could have a hard time prosecuting other trademark/copyright infringements.
Few people read the T&C documents. Fewer still actually understand the meaning of the text, and even fewer the potential consequences. The South Park "HUMANCENTiPAD" episode should be required viewing for all who wish to click through an agreement.
People using the Poli 'service' I mentioned elsewhere in this thread don't realise they give Poli the right to access your bank account, store your bank account information (balances, deposits, withdrawals, statements, login times etc etc etc) because they trust the face-value without thinking - 'government site uses this so must be OK', or worse the cheap convenience factor - 'bigbox store uses this so I can pay them and just pick up the bits from the front counter'.
The levels of stupidity still amaze me. Used to be that people would give away just their password for a chocolate bar, now they give away their full log in info for the picture of one :(
