Let's take Slashdot as an example. I am posting using my account, but there is no automatic way for this account to be linked to me the legal entity. In respect to this proposed law would this count as an anonymous post? If this is a back door to forcing people to link all their online activities to their real life identity, that would be a major problem.

I presume that 4+3+2=( )+2 is supposed to mean the same as 4+3+2=x+2.
If they had presented the equation with x, surely (almost) everyone would have solved it?
I'm from the UK, is 4+3+2=( )+2 a commonly used / commonly understood way of presenting the problem in the US?

The headline suggests that China is using import rules to bolster security. I think it is the other way round. They are using the demand for source code as a barrier to trade to (unfairly) help domestic firms.

Why do people write like this?

Your points about companies being reluctant to give bad reference is well taken, but where did the 'black people' rant come from? You seem like one of those people who suddenly butt into a random conversation with lines such as 'What about those blacks eh?'. It just leaves everyone else embarrassed and slightly bemused.
