Speaking of the pollution, this is what I get when installing electrum on gentoo (well, it is calculate linux really, but same source basically):
 * Messages for package net-misc/electrum-4.4.3:

 * If you are new to BitCoin, please be aware that:
 * 1. Cryptocurrencies are volatile.  BTC has been subject to rapid
 *    changes of value in the past.
 * 2. Cryptocurrency ownership is determined solely by the access to
 *    the private key.  If the key is lost or stolen, BTC are unrevocably
 *    lost.
 * 3. Proof-of-work based cryptocurrencies have negative environmental
 *    impact.  BTC mining is consuming huge amounts of electricity.
