I don't like large companies using basic words for their business. They take complete control of all trademarks and screw anyone who has anything similar.
You want to call your band "new kids on the block" or your game "blocks"? Sorry there is a trademark on block and it's "too similar" to what we do. You don't agree? Go ahead sue us, oh BTW we have more money than you...
They absolutely should never be granted trademarks on such common words in the first place. The intellectual property system has become another example of regulatory capture, ready to be abused by those with deepest pockets.
