I am an advocate of E2EE, but your argument is a little thin I feel. Let's turn it around. Imagine if law enforcement were completely unable to enter any home, even if they had a warrant to search it and reasonable suspicion that there was incriminating evidence inside. Anyone could do anything they wanted and as long as they kept the evidence inside their home there would be nothing law enforcement could do about it. The arguments in favour of there being some way for law enforcement to be able to search messages when they have a warrant to do so are certainly worth considering, and (for what it's worth) I feel the sentiments in the open letter strike a good balance; but, I also feel that what they want is, currently, impossible without compromising security for everyone.
