        A misconception, it was the EU's commissioner for the internal market 
Thierry Breton 
(https://ec.europa.eu/commission/commissioners/2019-2024/breton_en) who 
technically is not a head of a country. And the twitter messaging with Netflix 
and Co. was the "PR leg" of a joint statement of the EU commission and the Body 
of European Regulators for Electronic Communications 
(BEREC)(https://berec.europa.eu/eng/document_register/subject_matter/berec/others/9236-joint-statement-from-the-commission-and-the-body-of-european-regulators-for-electronic-communications-berec-on-coping-with-the-increased-demand-for-network-connectivity-due-to-the-covid-19-pandemic)
 aimed at european ISPs giving them guidance how to deal with potential 
congestion due to shifted traffic pattern caused by the mitigation approaches 
to limit COVID-19 spread. Reading that makes it clear that the EU accepted that 
in the current situation, the goal is not to let the consumers feel the quality 
differences between different ISP
 s but give ISP exceptional temporary permits to shed network load in line with 
the EU's net neutrality regulation.
In a sense the EU was presenting the thumb-screws and laid out under which 
conditions they might be used. Most of the streaming media companies read the 
signs correctly and decided to pro-actively reduce their bandwidth use on their 
own terms, instead of risking indifferent packet dropping by ISPs...
        IMHO both sides, the political/regulatory and the private enterprises, 
acted quite rationally and efficient. The fact that there is currently no 
wide-spread network overload does not make it a bad idea to pro-actively take 
measures to reduce known bandwidth hogs... Honestly, that is what I expect from 
halfway decent policy makers, address issues before the house is on fire (but 
hey, I also consider how the Y2K situation resolved, not to be a sign of 
undeserved alarmism, but rather successful mitigation after realization of the 
importance of the issue).

        Nope, at the time of the twitter message disney+ had not started 
serving Europe yet, Disney came around promising to pro-actively reduce their 
streaming bandwidth by 25% even before starting.

        Sorry, the joint statement explicitly tackled the issue of how to shed 
overload in compliance with the EU's net neutrality rules and regulations. Now, 
you might not agree with the taken decision, but that is different from the 
questions you posed, no?

        Again, that was the PR side, the "meat" is/was in the clarification to 
European ISPs how to shed load in compliance with the EU's NN rules.

        That is not true today, ISPs and CDN's as far as I know already use 
SLAs to prioritize e.g. VoIP traffic at peering points, so we already have more 
than best effort for the few things where it matters?

> - The Internet MUST NOT be able to further distinguish traffic.

        IMHO that is a sane approach because traffic carries very little 
reliable information to meaningfully distinguish traffic. Sure in an ideal 
world an overloaded hop would divine which packets are least important and 
target queuing/dropping to those while keeping important traffic fast. Alas, 
the required oracle seems to be amiss... Also note that NN rules where pushed, 
because ISPs where playing games with treating traffic differentially with the 
sole goal of extracting more revenue/income out of the same amount of traffic, 
is that really what we want?


> - Its just a matter of more money to eliminate inacceptable congestion.

        That hinges on the definition of "inacceptable", but sure money will 
allow to increase "bandwidth" and hence reduce congestion for the same amount 
of traffic (or move the point of congestion to some other place).

        What alternative do you propose instead?

        Mmh, Showtime only serves the US, and HBO only serves parts of Europe, 
but assuming you get their content streamed to a receiver in Europe, according 
to EU commission and BEREC that data could still be subject to throttling (I 
guess you would need a VPN and hence in practice would avoid being limited).

        No, we have big quasi-monopolies because economists and so-inclined 
politicians for decades have chiseled away at antitrust regulations... (I find 
it delicately ironic that the same people who preach "free market" typically 
are the first that welcome approaches to side-step the market. It is the same 
"experts" that simultaneously only see limits to what is okay for a company to 
do by regulations and the law AND work hard to get rid of regulations and laws, 
but I digress).
