Even what the media does choose to report, it dramatically lessens the estimates of crowd sizes (by multiple orders of magnitude - I wish I were joking here but no).

Also there are multiple organizations doing the organizing, so lack of a listing in any one of them does not indicate absence of an event.

The media has never been more biased, it would seem. They report whatever they think will maximize profits and please their oligarch overlord who purchased them the most. Capitalism working as intended, actually. Hence the need to check multiple sources of media or spend a GREAT deal of time, energy, effort, and most costly of all, attention, figuring out which ones to trust. No I have no idea who it is that can be (none? hence back to checking multiple, and correlating with primary sources as well).

It is no surprise then that you are seeing a biased picture... by design.
