I have several thoughts on this:

1. Maybe the Q team became an intense target of the cabal that they didnt worry about in the beginning so much because the following of posts the first couple of years was not millions of people. Congress said it was fake, the media claimed it was fake, and at that time they thought that it was enough to "debunk" and portray "qanons" as conspiracy theorists,

2.maybe It intensied to the point that Q decided to stop posting or the powers that be discovered identities and shut down the comms.

3. Q team several times said "we have it all" which one could take to mean that everything we need to know has been said already and there is no need to post more which could lead to discovery and possibly jeopardize operations in the plan. Or we have it all may refer to Q "having it all" in terms of evidence and power to see the plan through.

4. We do have it all, we have proofs, deltas, and the ability to discern and research double meanings, red flags, and misinformation so Q has stepped out of the teacher role and into the "action" role.

Whatever the case I cant wait to see who has been talking to us!
