You can propose changes to the network at any time via a BIP (Bitcoin Improvement Proposal) [1], so sorry, but you're just wrong. Bitcoin is the most ethical form of money that has ever existed.

This is an impressive contortion of reality, but nonetheless completely wrong. Your "voting" ability has nothing to do with participation in mining. Your vote is participation in the network, open ability to submit proposals, run a node to bolster the network, and if you wish, run a mining rig to validate blocks and earn Bitcoin. You can also earn Bitcoin from others directly providing products and services.
For both Bitcoin and Etherium the original white papers do not paint a full picture of the state of each cryptocurrency. Here are a few links I recently read on both BTC and ETH:
Bitcoin Wiki: https://en.bitcoin.it/wiki/Main_Page
Bitcoin BIPs: https://github.com/bitcoin/bips
Etherium Website: https://ethereum.org/ (it has a lot of information spread all over it)
ETH2 Beacon Chain Blog Post: https://ethos.dev/beacon-chain/
There's a lot more literature that you can find via Google but it's spread out all over the place.
I never heard of all of this having happened. To my knowledge Bitcoin's scripting language was not trimmed, it was in fact extended over the years by various BIPs [1].
What's your source for these statements?
This statement betrays you have not paid attention to the numerous improvements made to the Bitcoin infrastructure over the last 11 years: wallets, nodes, exchanges, payment processors, vaults, blockchain upgrades, basically all the BIPs https://github.com/bitcoin/bips : segwit, P2SH, lightning, M-of-N keys, deterministic wallets, etc. Using Bitcoin in 2020 is nothing at all like it was in 2009.

When you upgrade your Bitcoin node software, the act of the upgrading is you casting your Yes vote for the changes introduced in that version. The BIPs etc. can help you understand these, but if you want to be 100% diligent, the only fully authoritative source is the state of (the code sources in) the git repo as referenced by the commit hash in the Bitcoin software you are upgrading to.
