You obviously do not know what you are talking about. You apparently think
that "all CSS" is some kind of "infection". Like a disabled telemetry, in
your mind (lol). Nobody browses the Web blocking *all* CSS, unless he/she is
masochist.
Let us take your website as an example: https://anchev.net
Its CSS is more than 10,000 lines long (!): https://anchev.net/home.css
Without it, your site becomes much uglier:
http://dcc.ufmg.br/~lcerf/anchev_no-css.html
I blanked all pictures. Although you told me in
https://trisquel.info/forum/web-browser?page=5#comment-127512 that I have "a
serious mental disorder" for distributing my scripts under the GPLv3+ (that
allows copying), I am afraid your judgment may suddenly change when it comes
to copying your pictures.
Anyway, *some* (not "all") CSS can allow third parties to track the visitor.
Like Google fonts taken from fonts.googleapis.com. However, if the website
uses Google Analytics, that does not make much of a difference for most
users, who will execute that proprietary JavaScript and be tracked (how
disgusting!). You know, like on your site: https://anchev.net/home.js
