Giving big tech access to E2E encrypted messages will give consumers a false sense of security while still selling their data. This has been discussed in the whole chrome incognito article (link). I cannot imagine a world in which big tech won’t use this data to try to sell more. Big tech will always be a business and a business’s goal is to make money in anyway possible. Governments on the other hand can use this to fight crime and stop abusers… but we would need to trust the government to do this appropriately and safely… me as an American have been fooled by this one too many times to trust the government to act appropriately with this data.
