Many companies and worse, public institutions around the world are moving to solidify the destruction of evidence with data retention policies. They may automatically delete any email older than 1 or 2 years, every instant message sent via corporate channels in 30 days, etc. as a "disk-space saving measure". Including backups! Anyone can see through that explanation since any CIO claiming cost savings come from the few tens of GB of archived Office Communicator chats should be politely invited behind the barn for a dramatic reenactment of an age old saying.

Scandals like Boeing's and others that shook trust in public institutions, most of which are required by law to make any such material available to citizens, just convinced them that proactive destruction of evidence is the way to go. This is not punishable by law. And when the requests for data do come in all the have to do is delay the process until the totally legitimate automatic policy kicks in and removes the last shred of evidence.

At this point only whistle blowers diligently collecting all the data before it's destroyed could still help in any way but this comes at great personal risk. And when tools like Signal are involved good luck with that, one would have to be part of every conversation.
