Privacy Issue #2622
From the projects website 
libgdata is a GLib-based library for accessing online service APIs using the GData protocol — most notably, Google's services. It provides APIs to access the common Google services, and has full asynchronous support.
libgadata is in
your-privacy-blacklist.txt (formerly known as
your-coherance-blacklist.txt) since commit 518631a55982f42e28bd4342d9354cd07463d57f .
The mentioned reason in the package:
provides support for unsafe and dangerous for privacy services
I tried to find some security issues related to it, but the ones I found (such as ) were closed before libgdata was blacklisted.
I looked also at parabola's mailing list at that time, but could not find more informations.
Probably the reason for blacklisting it is the google dependency. I think this could be a good moment to re-evaluate libgdata and (at least) clearly state why it is blacklisted.
Packages that depend on libgdata and are blacklisted today:
|claws-mail||x||optional depends of libgdata|
|eog-plugins||x||depends of libgdata|
|evolution-data-server||x||depends of libgdata|
|gnome-documents||depends of libgdata|
|gnome-online-miners||only useful with libgdata (provides support for Facebook, Flickr, Google and SkyDrive)|
|gnome-photos||depends of libgdata and gnome-online-miners|
|grilo-plugins||x||optional depends of libgdata|
|libgdata||provides support for unsafe and dangerous for privacy services|
|shotwell||depends of libgdata and contains support for Facebook, Flickr, Picasa, Tumblr, Yandex and Youtube (Note: Youtube option has support for registered users only)|

- Status changed from confirmed to info needed
- Description updated (diff)
unfortunately, many of the entries which were added to the blacklists in the early years of parabola, were not well documented, if documented at all - i have added some sanity checking to the blacklist generation script, to reject entries which do not specify some brief rationale and an associated bug report it would be a lot of work to re-evaluate all of the incomplete entries though; so that code is yet to be used - i have been trying in recent years to clarify them whenever i have reason to wonder myself - hopefully, they all will be clarified eventually; but in this case, i also could find no discussion about 'libgdata' - we should probalby elect this ticket as the bug reference for the 'libgdata' entry
i can only assume that there was some clear justification for each entry; but such vague rationales as: "it's unsafe and dangerous" should not satisfy anyone, as they fail to convey the justification, to both users and future maintainers
unfortunately, in this case, the upstream description is not much more helpful
based only on the upstream description, it is not evident that this is a privacy concern, in that it is probably not itself an anti-feature, though it could possibly be used as one by some clients - also, it appars to be an interface to web APIs, which often require each user to configure their personal credentials, in order to be useful, even to access public data, which is all that most clients would want to do with them - if that is the case, it is clearly not an anti-feature; because it would not be possible to use it unintentionally - ironically, that frivilous requirement is the very thing that diminishes it's potential as an anti-feature
for those reasons, it should probably be removed from the blacklist, and each of its clients should be evaluated instead, to determine how the library is actually used - for example, if some client uses it to make un-attended connections (of the "phone-home" sort), then it could be considered as an anti-feature of that client, but not necessarily the libary
to add the the mystery, the blacklist entry for 'shotwell' supports the assumption that manual configuration (therefore explicit consent) is required; though the entry for 'gnome-online-miners' suggests that the other services are supported via 'libgdata'
for a concrete example, totem, as mentioned in the upstream description, uses it to search youtube (totem is not blacklisted BTW) - that is a legitimate use-case, and probably not a privacy concern; because presumably, it is only used if the user has firstly configured their youtube API credentials, and accessed only when the user explicitly searches youtube at runtime
for a practical example of a blacklisted package, i looked into this because i rebuilt 'claws-mail' - the arch 'claws-mail' package has 'libgdata' only as an optional dependency - the parabola 'claws-mail' replacement removes the optional recomendation and intentionally compiles out the ability to use 'libgdata' - as 'your-privacy' currently conflicts with 'libgdata', it necessarily precludes that functionality from activating anyways, even while using the arch package; so it seems to me that there is no reason to blacklist 'claws-mail'
again, i think that the best plan moving forward is the opposite: to determine if 'libgdata' may be removed from the blacklist, and only clients which use it as an anti-feaute would need to remain blacklisted
