Agreed, this is a valid list of minor concerns but this is just a fearmongering post. It’s not good that some metadata can leak but if you take normal precautions (i.e. don’t run this next to your classified information storage) it’s fine to open this so your friends can watch media.

Source: me and my Masters degree in cybersecurity (but apparently OP just learned about Kerckhoff’s principle and rainbow tables in a completely incorrect context so I know how to do my job or smth lmao)

Edit: lol don’t look at OPs post history, now I know where the fearmongering came from
