TC have always been long and legalese and it wasn't because of GPDR. I can't find your examples in the T&C, it seems to be about 'privacy notice'.
Am i supposed to read that too and keep up to date? I signed up in 2003, do you mind showing me what i agreed to?
And out of genuine curiosity, 'any information' seems to be a superset of 'personal information', isn't it? what is "any information"? and are you saying amazon is only using personal information (which is what, exactly?) to display ads?
Amazon is much better than most. You can read historic t&c's. That said, you have a big misunderstanding. If you have continued to use the site, all T&C's updated based on continued use.
That said, amazons are pretty darn clear.
"We receive and store any information you provide in relation to Amazon Services. "
"We use your personal information to display interest-based ads for features, products, and services that might be of interest to you"
