Note: I assume “English” rather than “British” law is correct here.

… Small non-British news outlets and humble non-British authors (…) are being suied in English courts by rich-mighty foes. The cost of litigation is so high ($200,000 for starters, and $1m-plus once you get going) that they cannot afford to defend themselves. The plaintiffs often win by default, leaving their victims humiliated and massivly in debt.

Now these numbers ($200k, $1m) given are legal costs for defending, not the awards if you lose. How can a relatively straightforward civil case take more than a thousand lawyer-hours for one party?
I understand that
[QUOTE=ibid.]
… Under English libel law, a plaintiff must prove only that material is defamatory; the defendant then has to justify it, usually on grounds of truth or fairness.

and
[QUOTE=Wikipedia: English_defamation_law#Modern_law]
…The allowable defences against libel are:
* Justification: the defendant proves that the statement was true. If the defence fails, a court may treat any material produced by the defence to substantiate it, and any ensuing media coverage, as factors aggravating the libel and increasing the damages. A statement quoting another person cannot be justified merely by proving that the other person had also made the statement: the substance of the allegation must be proved. The defence fails if the statement concerns spent convictions.[1]
* Fair Comment: the defendant shows that the statement was a view that a reasonable person could have held, even if they were motivated by dislike or hatred of the plaintiff.
* Privilege ...

so the burden is on the the defendant to prove usually the truth or the quality of a fair comment. Still, why would such a civil defence take thousands of hours to assemble and argue? We get (the civil-law equivalent of) libel trials in Germany too (even criminal cases), and the defendants grouse about the verdict being unjust or the award/punishment being too high, never that I have heard of about being bankrupted by their defence cost.
Also, civil litigation cannot be that costly in the UK in general, or nobody could sue or defend normal cases like “Your defective plumbing flooded my apartment” or similar.
