If you work in a big corporation and have to implement a feature for web site and have to support only a certain browser, for example IE 8 and get something done until 5 p.m in the allocated time., do you think that
a) what about the the users who have installed the other browsers? Should I spend the next four hours doing unpaid work to support those as well?
b) go home and spend time with my family/watch a movie/drink a beer/go to a bar
I think the answer is pretty clear.
Nice summary there, painting the CSIRO as some kind of patent troll. They never claimed that they had "[invented] the concept of wireless LAN", they claimed that they had developed some very clever algorithms dealing with rejecting interference and the like.
The frontpage of CSIRO says "Wireless LAN, CSIRO's #1 invention, is estimated to be in more than three billion devices worldwide.". That doesn't sound like they just invented some clever algorithms.
Like the parent said, time itself did not exist until the big bang, therefor, there is no "before" the big bang.
