RC4
It is easy to not use it.

You simply remove it as an option from your list of availeable cyphers.

The troubling part is that to exploit alot of these weakneses in the past you would have been a nation state player or had access to MITM data points.  Now you just need access to the data stream and some gear to do some computing.  So as the playing field levels down to the criminals ability to have nation state capabilities we finally decide we have to fix the problem so we don't get robbed and lose some real money.

 

Sadly we did not care if we were spied on, now we care that we can be robbed.

Re: Legacy Uses?
What's most interesting here is how these outdated -- and weak -- options continue to be included in SSL/TLS implementations. There may be a legacy or backwards-compatibility reason, but the bottom line is that it leaves users and companies vulnerable. The good news is the next version of TLS aims to be a leaner, meaner spec that doesn't carry this type of baggage. Of course, in the meantime, older versions remain vulnerable.

Legacy Uses?
What still uses RC4 (business case)? If its no longer needed I don't see why an update shouldn't be sought out to remove it?
