Every encryption is end to end if you're not picky about the ends, or metadata. Do you trust facebook (excuse me, meta) to not snoop on your messages, and to not share them with the "intelligence" agencies ?
This is not true. The IETF draft is explicit that E2EE means that the message cannot be read by any party other than the sender and the intended receiver. When companies like Meta claim they support E2EE, this is what they claim. There are no tricky semantics or legalese at play here.

These requests of data collection are perfectly legal. FBI DITU gives an order: give me all chats from *@banana.com and they receive banana.com.
From there, two choices from the perspective of a tech provider:
a) You accept. You get paid.
You can always claim you had been coerced / are a victim, and that everything has been done by the law.
You take the risk to lose over 250K per day (!) in fines, some other court scandals that will come to you, some shady private stuff (what if we learn about your secret jacuzzi ?), harassement of the team, be publicly shamed that you supported terrorists who caused actual death of Americans, etc.
In addition, nobody will know that you are the privacy hero and you are not even sure that the data is not exfiltrated another way.
Yes, we looked carefully and decided we won't enjoy losing 100M USD and go to jail.
The trick is that the identifier / wildcard can be very vague and wide. Or there can be multiple of them, each of them are narrow, but put one of top of the other they are super wide.
