I can't stand technical jargon or people who use without regard for their audience.

The only purpose of jargon is to make a conversation exclusive to only those who know the language. If your purpose is to educate or collaborate or truly communicate, then jargon is harmful.

Legal jargon is probably the worst example.

Jargon is just a time-saving and precision measure. Try doing without it sometime - it's painful.

It is totally unavoidable as long as people keep communicating with words. The better solution is not to complain about it, but to ask for definitions (recursively) - and then you can reap the time-saving and precision benefits of the terminology, too.
