I think its because the law in the UK limits exclusions of liabilities in consumer contracts far more than in business contracts (in general consumer law has a LOT of protections that do not apply to business contracts). If you look at the clauses excluding liabilities they are very different. I think the same applies to many other countries so they will also have separate consumer contracts.

The law in Australia also has teeth, but visiting the link above just gets me (what seems to be) the US version of the terms without anything around commercial use.
