As a DEVELOPER of proxies, I'm aware of the advantages of proxies, and
you don't have to convince me.

But as a developer of proxies, I also know quite well their
disadvantages, especially when they are transparent, without giving any
choice to the user, and when any type of site must pass them, no matter
if it uses things that are problematic for a proxy (in this message I
don't relate to reverse proxies, of course).

I can count some main problems:

1. Many sites use non-standard HTTP things, that confuse proxies.
2. Many sites have a long delay in the middle of the response. In some
   cases, proxies interpret delays as timeouts, and cancels the
   transfer.
3. When you upload pages to a remote site, or modify a remote site, or
   do any other remote maintenance of a site, you get the old content,
   no matter how many reloads/refreshes/cache-clean/etc. you do.
   Sometimes you can use HTTP headers to expire the page and uncache
   it, but usually it is not possible.
4. Nobody wants to read old news, especially today in this country.
   It is not so nice to read, a hour after a terror attack, that a
   terror attack happened "a minute ago" (although professional sites
   avoid such ambiguous language).

I can count many other disadvantages of proxies.

I am not against ISP's; the opposite is the truth: I think that their
prices are much lower than their costs. And I am even willing to pay
extra for not passing proxies in my way (of course, reverse proxies are
a different issue, have many advantages, and almost no disadvantage).

I just want to choose my ISP according to this parameter.

P.S. I lost 2 hours, today, because of a transparent proxy.
