Amounts to the same thing. When you put money in a bank, you are effectively losing control. It's a gamble in which you hope you make a profit from interest rates. The banks can freeze your money from 3 to 12 days so that you cannot withdraw - they do this regularly and blame it on "clearing times".
I don't think that it is the same thing, since most people affected will have deposited their money for a fixed term or fixed interest rate not invested speculatively. In fact speculators will not be affected as they will have their investments in stocks and bonds, not cash. Bank's can change the terms of interest they pay, but then under normal conditions the investor has the choice of moving the money elsewhere.
According to reports, they will get shares as their "profit" - so if it replaces the interest rate fairly, what's the problem? Isn't this a bit like when the UK government privatized Gas etc - they gave shares to the owners (taxpayers) instead of money and they could sell the shares on to release the money.
The purchase of privatisation shares was voluntary. As a member of the public you 'owned' the utilities being sold. Regardless of whether you agreed with the government or not, after the privatisation you now 'owned' the money that was paid for them. This 'share offer' is not voluntary.
