FFS, those do not require active monitoring. Article 17, formerly known as article 13, explicitly states: "8. The application of this Article shall not lead to any general monitoring obligation. ".

general in that statement is a weasel word, and including it in the official article text is a clear indication of intent:

"Yes, we recognize this requires setting up a monitoring infrastructure for compliance with the article, but we reserve the right to publicly condemn any company that uses that same infrastructure for self-serving purposes."

Lol. Then how else can it be followed?

You could, you know, read the article before you start spreading FUD about it. Maybe the answers you seek are in it.

In the end it doesn't matter how it will be followed. If general monitoring is the only way to follow it then nobody needs to follow it. Simple as that.

Time will tell. Sadly, in my read, "no general monitoring" and "mandatory upload filters" are not the same, and thus, not mutually exclusive.
