Mayanaise has given you good advice.

I'd review your email before you sent it if you'd like. You write it up as best you can, and I'll review it for clarity and tone. Just cut out the account names and other identifiers I shouldn't have.

never had issues with humble and i dont really understand what your problem is all about.
never heard that they ban accounts just because you didnt use the keys, that sounds quite fishy.
you either traded keys or sold them.
and about the ToS, they are usually in the right lower corner on the majority of websites / shops. nothing wrong with that.

and to compare humble with north korea or the udssr/cccp which are now countries with their own leadership btw (more or less) is just outrage

I do not understand which part of the ToS you've been broken, according to HB. Reselling for example was against the ToS right from the beginning or at least since I am around there (before 2019). I acknoledged people, who had trouble with HB using the gifting-option to much, which is easily bypassed with generating the key and send the key directly to a winner of Steamgifts or a trading partner.
I guess you might follow Mayanaises adivices and see, what you can do. Hope you get your keys back.
Although I can understand your anger, your comparison is not even close to be valid. It's capitalism, it was never meant to be humanitarian.
