One thing that should be noted is that, since the Parliament has been able to approve an amendment by absolute majority (which explicitly excludes E2E chats), the procedure is not over and the law is still not enacted, a third reading is still needed, after negotiations with the Council and the Commission, and in this case the Parliament will be able to reject the act by a simple majority
The new reading will happen if the Council rejects the amendment approved by the Parliament. When it does they have 6 weeks to negotiate, and then 6 weeks to approve the result of negotiations, if any.
Basically, the hope is that the Council rejects that amendment in its second reading (but right, the probability of this is not really high, since it codifies what was already true). I should have explained it better in my comment
