Changing the terms

Why is it OK for Uber to change the terms and then offer 21 documents, many are over 35 pages, rather than highlight the changes?   For someone like me, that could take days to read and frankly, I would not know what has changed.  There should be a place to go where we can see only the changes.  If you need to get back to work, and try to pay bills (when they are offering rates so low it is more like $5 an hour net) who has time to read all that crap... and it is written very meticulously to confuse people.)
