Sometime ago I found an alternative "OS" for my DNS-320L called Alt-f [0]. Granted its UI is very old-school but it has worked flawlessly. There has been no release since 2022 but at least it's more recent than the last official firmware (and I assume is not impacted by the vulnerability).
IIRC I didn't even had to format or move the data I had on it before installing.
I think at some point you "forget" what some emoji really mean. I've kept my circle of friends quite small in the last couple decades, and we're all using this emoji for sarcasm. It's akin to private jokes, that crack you and your friends up every time, and then when you try one of those with other people, you're the only one laughing.
My other colleagues were not confused by my usage of the emoji, although they've known me for some time now, and they know that I'm not the type of person to actually roll my eyes while talking to someone, or even look down on them.
At least it was a nice reminder that our ways, customs and habits, no matter how normal they seem to ourselves, can still look crazy from the outside.
But I agree with you, it may have been one of the best sentence to use this emoji with. :)
Emojis can have ambiguity too. My friends and have been using the eye roll emoji to signal we're being sarcastic for about 10 years. The un-animated version of this emoji looks like "I'm not really thinking what I'm saying", especially on Discord/Twitter.
I've recently a colleague who used the tongue out emoji for sarcasm and the eye roll one for, well, eye rolling with disdain in reaction to something.
The first chat discussions were then quite awkward, because when I were to write something like "You should have tested your code before deploying it... :eyeroll:", he was thinking I was openly looking down on him in front of the team.
We had to have a real discussion about it. It made me tone down my use of emojis - and sarcasm. I suppose using animated emojis (they were in MSN I think?), or GIF reactions would have made the things clearer.
IIRC they also allow charging the person - for a "reasonable" amount - for the data retrieval process (which I assume would include the "identity verification" part).
Maybe using the 3-D Secure protocol (especially the second revision) would be enough to unburden yourself for verifying the identity as Mastercard/Visa/American Express supposedly check it for you.
This would work only in some conditions (the data subject should have a card to their name that supports 3-D Secure protocol, and you need to had a complete payment platform to your website/app/whatever) and doesn't solve all the other problems we have (like being sure we are delivering the right information esp. regarding homonyms and so on), but that could be something to investigate.
IIRC I didn't even had to format or move the data I had on it before installing.
