If the terms were so clear on Saturday, why has the wording now been changed by the casino?

Any way you read it anywhere in the world, the sentence:
"When you make your first deposit of up to $100, we'll credit your account with a matching bonus of up to $100 FREE"

The point i'm trying to get across is this casino will change whatever is needed for it's own benefit. Previous posts on this forum have been in a similar vein where the casino has altered various
T&C
's to avoid payment of legitimate winnings.

How would you like it if you went to the bank on payday to draw out your wages, only to be told "sorry, all your cash has gone, we had to change the interest rate this afternoon......."
