At first, reading the headline, I thought that the WT had received that money from the UK government. That would be a huge scandal. Voluntary donations from the R&F, not so much. They're free to donate their hard-earned to whomever they like.
If that figure is true, a quick back of the envelope calculation reduces that amount to about $630 per year per witness, or about $52 per month. $13* a week. That's not a huge amount for individual donations by a practitioner of any religion.
The headline figure is breathtaking, but not so much when its broken down. It's a tad dishonest, IMO, to telegraph figures in that way. You see this sort of reporting every day: "Government to spend $10bn tackling (cause du jour)!" screams a headline. But when you read the article, it's the total amount budgeted to be spent over the next X number of years. Not such a big figure then, is it?
Don't get me wrong, I hate the control that the WT has over its slaves (their term, not mine). But try to keep things in perspective. A lot of people spend a lot more than $13 a week on cigarettes or lottery tickets. While I don't personally approve of the average JW's "vice" of giving money to the WT, it's their choice.
