These are far from the worst patterns. I've seen so much awfulness out there. My favorite recent one was a renewal if you don't cancel by a deadline that's months ahead of the actual end of the contract period and it also had a substantial rate increase and all the language that we supposedly agreed to wasn't actually present in the contract we signed. Those terms were in one of those "incorporate by reference" claus…
Does it actually work? Have you tested in in court?
But in real life what it really does it get them to back off and go back to having a normal negotiation about what we do want to do for renewal instead of the bullshit attempt to mislead and trap us.
Needless to say if there's any viable alternatives to companies that do this we take them but in some categories all the options suck.
