Does this apply to cookies? I am asking because lot of websites have "necessary" cookies and there is no way to opt out of them (other than by closing the tab), and if there is and you do, then you cannot proceed further. I really do not understand why some cookies would be necessary to view a page though, but I have seen this on A LOT of sites.
Example: https://edigital.sk
On the right, you will see a down-arrow, click on that. You can clearly see the first checkbox on the left being checked and disabled, it is the "necessary" or "essential" cookies to what I am referring. You cannot deselect. On top of that, there is no way to close the popup (?), it is by design. Of course there are ways to circumvent it, but that is besides the point.
There are many other websites like this, but I cannot remember them. :/
I suppose most of the time the box is there to allow you to consent to additional cookies as well.
There are also a lot of broken implementations out there.
You must click on "Continue with Recommended Cookies", or you cannot use the site (you could use uBlock to block the element, but that is besides the point).
While it clearly could be implemented many different ways, and I agree Dropbox should do better in this case, I think this is one of the difficulties in enforcing something like GDPR. Almost anything could be made to work in an anonymous way, so where do you draw the line? When signing up for Facebook or an email account, for example, there is no reason they need my phone number. Sure, they say it is for password reset purposes, but there are other solutions for this, or I can simply agree not to be able to reset the password for that account... etc.
I'm honestly curious, which part of the feature requires every user to know every other user who has viewed the page?
Clearly it doesn't have to and should not be this way. My point was that:
1. They are saying that their particular implementation did require it to be this way. 2. Almost every web app could be made to require less private data from the user, however if this is something that GDPR is going to enforce then there will end up being some subjective analysis (according to non-tech lawyers?) as to whether a particular implementation was in violation.
