Twitter’s new temporary tweets (“fleets”) idea doesn’t make much sense to me.
It’s well established that once something is published widely to the internet, it is not reasonable to then have any expectation of it disappearing completely from existence.

Twitter itself, the platform, may be choosing to no longer display an expired fleet, but that begs the question of “what is the ultimate purpose of creating ‘fleets’?” There really is no legitimate user problem solved by the temporary fleeting-tweet concept.

It’s obvious to me that the end result will be:

1. the average twitter ‘fleet’ user lulled into a false sense of “oh, I can be more loose in my wording because this message will disappear”.

2. Twitter still retains the same amount of messages and user data they always have (but makes less of it viewable to the public due to the “natural” “disappearance” of fleet-tweets.

3. Badguys, like propaganda botnets, will benefit greatly as they no longer have to cleanup after their own misinfo/disinfo tweet campaigns.

4. Those same malicious entities gain plausible deniability because their operational IP address did not have to log back in and actively delete those previous messages in order to hide the evidence from eventual investigative public eyes.

5. Anyone piecing together open source bits of info, to uncover vital evidence of harmful campaigns, is hamstrung by twitter providing this new gift of automatic covering fire for the bad guys.
