And when my "Reddit energy consumption" rose because they migrated from old.reddit.com, to their new bloated frontend, that's _my fault_, right?

It is because you know this and you continually choose to keep using it.

It’s be like if your 2001 BMW car was super fuel efficient, and then for whatever reason the 2028 model guzzled gas and you chose to buy it anyway

Just because the thing you did once upon a time was efficient, does not mean you have a lifetime pass to engage with it no matter the updated circumstances
