Main points:

1) Huge majority of nodes are owned and operated by intelligence agencies. Nodes not operated by agencies are actively suppressed (another case this week was reported). That "node hoping" feature is pointless when you control enough nodes and apply timing monitoring on the "anonymous" requests.

2) the connection mode of Tor is seriously outdated and flawed. Establishes a single path using "best speed" which makes it easier to monitor the traffic. Even if they wouldn't know the content (which they do), they know your IP address and which sites you are visiting

People tend to say "https" keeps communications safe. But they forget that on government level you can legitimately spoof certificates and reroute your traffic using MITM when your IP is interesting enough for them.

3) Multiple leaked documents from agencies show their investment on these topics. This was literally created and is funded by them every year (even Wikipedia details that), why wouldn't they track users?

In essence: it is a glorified government VPN. There exist better options such as I2P and yet you will see federal employees actively promoting Tor around here, along with naive developers/users who don't really know anything better.
