  "textContent": "Thank you for your information about Line and your perspective!\n\nGood to know contact discovery can be turned off and it prevents other people finding me on Line.\n\nE2EE enabled by default is a good thing, but since it is not mandatory some users may disable it. This possibility makes my friend’s contacts who disable it a (very small) security risk. As long as my friend wouldn’t forward our messages to their contacts, the fact it is not mandatory would not be a problem. All my friend and I would then need to do is avoid features that don’t support E2EE. This is not a concern in Signal where E2EE is universally mandatory across all users and features.\n\nURL previews has a mention in the Letter Sealing support page.\n\n> If your device were to access a website directly to create a URL preview, you would be at risk of being tracked (e.g. your IP address being acquired) by the accessed website and others. To prevent this and protect your privacy, we use a secure mechanism where LINE servers access the website on your behalf and generate the preview.\n>\n> Note: Due to this security feature, URL information is processed on our servers. However, you can turn it off via your settings if you desire.\n\nI interpret this as the Line server fetches the URL, thus URLs are leaked to Line corporation. Line’s justification is reasonable but it just transfers the risk from ISPs to Line. Either both my friend would need to disable URL previews (this may be possible) or they would need to avoid typing/pasting URLs into the text box (this is error prone and restrictive). For comparison I don’t remember how Signal handles URL previews.\n\nAbsence of disappearing messages in Line is a problem but not much different to absence of disappearing messages in email, thus both options are equally bad in this regard.",
