I think you mean... “It is hugely disappointing that Meta is stopping us from spying on their users."
... And children!
Even worse, having the government monitor your communications _destroys your life_.[1]
These proposals by governments are effectively saying, "We're going to protect your children using this technique that completely fucks them up."
Child abuse is one of the most horrific things there is. It's only second to even now horrific things things like let's let the government monitor everything all the children say.
[1] "Anything you say or do can and will be used against you in a court of law", as US residents should be well aware.
There is nobody who is "safe" from a company jacking up the prices of every product you see because you mentioned getting your paycheck in a message. Even if you don't say it directly, it can be implied from your general behavior using the same messages.
E2E encryption is a big headache for legitimate law enforcement. We've seen it with Encrochat.
It was a big issue but they still manage to get in, with difficulties. Now, E2E encryption is much harder to crack if possible at all. You probably need to compromise each specific phone/computer/app you're interested in.
Encro was a home-brewed system that pretended to be more than it was while the target market would have been much better off with an up-to-date stock android or iPhone handset + Signal and basic security awareness. The vulnerability around the handset is certainly significantly less than whatever cobbled together android distro they were using, and if the messages are on the handset then they are always vulnerable to recovery.
So is the requirement to have a warrant before barging into someone's house at 0300 with guns and dogs.
So is the requirement to allow the accused to confer with an attorney.
So is the prohibition on using torture to extract confessions.
And?
The world doesn't exist for the convenience of "legitimate law enforcement", or shouldn't, anyway.
You are comparing apples and oranges for dramatic purposes.
Of course police need a warrant e.g. to wiretap but that becomes moot if the wiretap is impossible for technical reasons. That is the whole issue here.
It is "obviously" nothing of the sort.
You're allowed to have curtains, no matter how inconvenient that makes it for police who want to look through your windows.
