I would personally be shocked if the EU voids click-wrap agreements for unconscionableness based on the process alone. I’m not super familiar with EU law; is that what it truly says? I rather doubt it because I do business in the EU and have been asked to agree to terms as a condition of making purchases online there.

Online retailers in the nordics occasionally try to post terms and conditions that contradict consumer protection laws, for instance retailers being on the hook for warrantying product(ion) defects for 5 years after purchases of products that ought to be durable, like electronics. The retailers win out on a substantial amount of the population not contesting it, but if you as a consumer go through the process the findings is basically always in your favor, despite there being agreements to something else. Telecommunications providers also have a long history of having their consumer invoices being voided for being unconscionable despite service agreements, especially in cases with children playing with devices (but otherwise also), going all the way back to the landline age.

Right. But those are substantively unconscionable terms, not about the agreement process itself.

sorry I did not phrase that very well, when I said as a general rule I believe I meant that if put to the test it could be often won on length alone in conjunction with the activity being done, but almost always these contracts are substantively unconsionable and of course people contest that, because most people don't get angry and want to fight for no reason, they do it because it is violating their rights.

As an example I have an email account with site A. I go to site A and log in, they suddenly spring a large new contract for me to read, I cannot get through to do what I came to do, it will take me 5 minutes to read so I click OK because I am on my way to check my email with site A. Procedurally this is not reasonable behavior.

What would be reasonable?

"Hi, we are changing our terms of service, you can see it at this link and agree. If you don't have the time right now you can do it later, but in three days you will lose access to the service unless you agree to terms."

There are however lots of other laws in the EU which may in fact make this behavior substantively unconscionable anyway. I certainly believe there would also be substantive arguments to be made in this case.

The council directive on unfair terms in consumer contracts puts every pre-canned contract in scope, and unfair provisions on a contract are rule non-binding (if the contract can keep existing after the unfair bits are taken out).

Right. But those are substantively unconscionable terms (“unfair provisions”), not about the agreement process itself.
